**MathGuru**, Tuesday, August 2, 2011 at 10:54amTry the binomial probability function:

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

x = 10

n = 20

p = 0.45

q = 1 - p = 1 - 0.45 = 0.55

Substitute the values and calculate.

An easier way would be to use a binomial probability table with the values stated above.

I hope this will help.
