Question 304714: 62% of men consider themselves professional baseball fans. You randomly select 10 men and ask each if he considers himself a professional baseball fan. Find the probability that the number who consider themselves baseball is (a) exactly 8, (b) at least 8, &(c)less than 8.
(a) P(8)
(b) P(x is greater than or equal to 8)
(c) P(x<8)
The formula is the part I cannot figure out how to solve.
Please help me figure out the formula and then I could work the problem.

You can put this solution on YOUR website!
These are binomial problems.
n is the number of trials
p is the probability of success on each trial
x is the number of successes in n trials.

The formula is P(x=k) = nCk*p^k*q^(n-k)
