Answer:
The question is incomplete, so I looked for similar ones and found:
<em>Of the 25 girls on the Alden Middle School soccer team, 40% also play on a travel team. How many of the girls on the middle school team also play on a travel team?
</em>
we can solve this the following way:
25 girls on the soccer team x 40% that play on a travel team = 10 girls form the soccer team that play on a travel team
we can also multiply (25 girls x 40) / 100 = 10 girls
we can check our work by:
10 girls / 40% = 25 girls in total

Its easier to find the complement of that instead
so you find the probability of 1 and 0
The .2 in the answer is the probability of each question 1/5
(10 C 0) x .2^0 (1-.2)^10-0=.1074
(10 C 1) x .2^1 (1-.2)^10-1=.2684
.2684+.1074=.3758 and that's the complement
so 1 - .3758= .6242
I too have a stats exam on this tomorrow lol
