**MathGuru**, Thursday, July 28, 2011 at 5:18pmUse the binomial probability function:

P(x) = nCx(p^x)[q^(n-x)]

n = 20

x = 10

p = 0.45

q = 1 - p = 0.55

Substitute into the function and go from there.

Note:

You can also use a binomial probability function table with the values listed to find the probability as well. It is an easier way of doing this problem.

I hope this will help get you started.
