What does a equal? a/15 = 4/5?

ratelena [41]

So in order to solve this we are going to cross multiply:
a 4
--- = --
15 5 so what were are going to do is we will take a and multiply it with 5 and we will take 15 and multiply it with 4. Now this gives us 5a and 60 so our new equation is:
5a = 60 now we are going to get our variable alone by dividing it by 5 and what we do on one side of the equation we do on the other:
5a = 60
÷5 ÷5 this gives us a=12
hope this answer helps

The probability is 19.88%.

This is a binomial distribution, because there are two outcomes, the events are independent of each other, and there is a fixed number of trials. The binomial distribution is given by:

$(_k^n)p^k(1-p)^{n-k}$

For this, n is 18; k is 5; p is 0.25:
$(_5^{18})(0.25)^5(1-0.25)^{18-5}
\\
\\=\frac{18!}{5!13!}(0.25)^5(0.75)^{13}
\\
\\=8568(0.25)^5(0.75)^{13}
\\=0.1988=19.88%$
