There are twenty marbles in a jar: some are red, some are
blue. You are blindfolded and choose two marbles. No matter how
you choose, at least one marble is guaranteed to be blue. Is it
possible to figure how many blue marbles are in the jar? If so,
how
many are there?

Answers

Answer 1

The number of blue marbles in the jar are 8.

Given,  the total number of marbles in the jar = 24.

therefore, total number of all possible outcomes = 24.

Let the number of green marbles in Jar be x.

therefore, the number of favourable outcomes = x.

The probability that the marble drawn is green  = x/24

But we have the probability of drawing a green marble = 2/3

x/24 = 2/3

3x = 2 (24)

x = 16

Thus , the number of green marbles in the jar = 16

The number of blue marbles = 24 - 16 = 8

Hence, the number of blue marbles in the jar is 8.

what is the probability that a single card drawn from a standard deck of cards is either an 8 or a heart?

Answers

The probability that a single card drawn from a standard deck of cards is either an 8 or a heart is 4/13.

Probability of an event E denoted by P(E) is defined as (number of favorable outcomes )/( total number of outcomes).

For example : the probability of getting Head in  single toss of an unbiased coin.  P(H)=1/2.

According to the given question

Total number of cards in a standard deck of cards is 52.

There are 4 suit in a deck each having 13 card each.

number of 8 card in a deck = 4

Number of hearts in a deck = 13-1=12      (-1 because 8 of heart is counted before.)

number of favorable cases of getting  either an 8 or a heart is 4+12=16.

The probability of getting either an 8 or a heart is [tex]\frac{16}{52} =\frac{4}{13}[/tex].

Therefore , the probability that a single card drawn from a standard deck of cards is either an 8 or a heart is 4/13.

The table shows the results of an experiment in which three coins were tossed.

Answers

The experimental probability that at least two heads would be gotten is 11 / 25.

The theoretical probability that at least two heads would be gotten is 1/2.

What are the probabilities?

Probability calculates the odds that a random event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.

Experimental probability is based on the result of an experiment that has been carried out multiples times.

Experimental probability = number of times at least two heads would be gotten / total number of tosses

( 5 + 6 + 6 + 5)/50 = 22/50 = 11 / 25

Theoretical probability = number of times at least two heads would be gotten / total number of possible outcomes

in a large population, 63 % of the people have been vaccinated. if 4 people are randomly selected, what is the probability that at least one of them has been vaccinated? give your answer as a decimal (to at least 3 places) or fraction.

Answers

The probability of at least one person being vaccinated out of four people chosen at random is 0.30, or 30%, rounded to the nearest hundredths.

What do we mean by probability?Probability is a branch of mathematics that deals with numerical summaries of how likely an event is to occur or how likely a proposition is to be true. The likelihood of an event occurring is a number between 0 and 1, where 0 indicates the event's impossibility and 1 indicates certainty.

To find the probability that at least one of them has been vaccinated:

In a huge number, 63% of people are vaccinated, leaving 37% unvaccinated. The point of concern for the probability that at least one of the four randomly selected people has been vaccinated. As a result, we must account for the possibility that one, two, three, or four randomly selected people were vaccinated.

We use P(1) for only one person; the same reasoning should apply to other subscripts.

P(1) = (63/100)(37/100)(37/100)(37/100) = 0.03089833P(2) = (63/100)(63/100)(37/100)(37/100) = 0.05094049P(3) = (63/100)(63/100)(63/100)(37/100) = 0.08398297P(4) = (63/100)(63/100)(63/100)(63/100) = 0.13845841

Adding all these probabilities given 0.3042802.

As a result, the probability of at least one person being vaccinated out of four people chosen at random is 0.30, or 30%, rounded to the nearest hundredths.

According to the question we have been given two parallel lines which is cut by a transversal line. There are total 8 angles and given is the measure of

∠4 = 5x + 35° and ∠7 = 45°.

We need to find the value of x.

Note that when two parallel lines are cut by a transversal then

i) corresponding angles are equal that is

                ∠1 = ∠5, ∠2 = ∠6, ∠3 = ∠7, and ∠4 = ∠8

ii) alternate interior angles are equal that is

                 ∠3 = ∠6, and ∠4 = ∠5

iii) alternate exterior angles are equal that is

                ∠1 = ∠8, and ∠2 = ∠7

iv) Consecutive interior angle sum is 180°

          ∠4 + ∠6 = 180°, and ∠3 + ∠5 = 180°.

Now using these rules we will solve this problem

Because of corresponding angles ,  ∠3 = ∠7 = 45°

Also ∠3 and ∠8 make a linear pair and sum of linear pair is 180°.

Therefore ,  ∠3 + ∠8 = 180°

                   45° + 5x + 35° = 180°

                     5x = 180° - 80°

                      x = 20°

Hence the value of x is 20°

the population standard deviation for the height of college baseball players is 3.0 inches. if we want to estimate 95% confidence interval for the population mean height of these players with a 0.68 margin of error, how many randomly selected players must be surveyed?

Answers

The number of players randomly selected is 381 and the standard deviation is 1.96.

What is the standard deviation?

The standard deviation is a measurement of how much a group of values varies or is dispersed. While a high standard deviation suggests that the values are dispersed over a wider range, a low standard deviation suggests that the values tend to be close to the mean (also known as the anticipated value) of the collection. The lower case Greek letter (sigma), for the population standard deviation, or the Latin symbol, for the sample standard deviation, are most frequently used in mathematical texts and equations to indicate standard deviation. Standard deviation may be written as SD. A random variable, sample, statistical population, data set, or probability distribution's standard deviation is equal to the square root of its variance.

[tex]Z(\alpha /2)=1.96[/tex]

Sample size = n = [tex][Z(\alpha /2 * \sigma/E) ]^{2}[/tex]

TO find: Values of θ.

Finding:

In the given equation: 2 cos( 4θ) - 1 = 0,

If the sum of two numbers is 88, then;

x + y = 88

If one number is 4 more than half the other number, then

x = 1/2y + 4
