Question 1131382
This is a binomial 12C7*0.3697^7*0.6303^5, the 12C7 being the number of ways they can win 7 games and then p^x*(1-p)^(n-x)
=0.0744

Binomial distributions are two choices, independent, fixed number and fixed probability.
to choose 3 from 5, it is 5!/3!2!, or 10 different ways.
12C7 is 12!/7!5! multiplied by the two below.
the next part is the probability of success raised to the number of successes desired.
then multiplied by the probability of failure raised to the number of failures.
This gives the probability of exactly 7.
There are binomial tables, and it can also be done on the calculator.
