Dan and Brian have played 51 tennis matches.
Dan has won 29 times.
Brian won the rest.
a) Estimate the probability that Dan wins.
b) Estimate the probability that Brian wins.

Answers

Answer 1

Answer:

A = 29/51   B = 22/51

Step-by-step explanation:

(E) =  number of favorable outcomes/ total number of possible outcomes

- number of possible outcomes= 51

- number of favorable outcomes= 29

therefore, P(E) = 29/51

- number of possible outcomes= 51

- number of favourable outcomes = 51 - 29 = 22

therefore, P(E)= 22/51

what number has 62 ones, 20 ten thousands, and 300 tens

Hope it helped you brainiest plz and thank you have a great day!!!

The number for the given statement is 203,062.

We need to find what number has 62 ones, 20 ten thousand, and 300 tens.

How to write the number into a word statement?

In general, use words to express numbers zero through nine, and use numerals to express numbers 10 and above. However, there are exceptions to this general guideline for number usage.

Now, 62 ones=62×1=62

20 ten thousand=20×10,000=200,000

300 tens=300×10=3000

Now add all these numbers.

That is, 200,000+3000+62

=203,062

Therefore, the number for the given statement is 203,062.

Step-by-step explanation:

[tex]\frac{7}{12} -\frac{4}{15} \\=\frac{35}{60} -\frac{16}{60} \\=\frac{19}{60}[/tex]

Answer:

[tex]\frac{19}{60}[/tex] or 0.3166667

Step-by-step explanation:

let's first make the denominators the same so it can be easier to subtract:

[tex]\frac{7}{12}[/tex] × [tex]\frac{15}{15}[/tex] = [tex]\frac{105}{180}[/tex]  and [tex]\frac{4}{15}[/tex] × [tex]\frac{12}{12}[/tex] = [tex]\frac{48}{180}[/tex]

so now we do:

[tex]\frac{105}{180}[/tex] - [tex]\frac{48}{180}[/tex]  =  [tex]\frac{57}{180}[/tex]  = [tex]\frac{19}{60}[/tex]
