**MathGuru**, Wednesday, April 3, 2013 at 8:38pmYou will need to find P(3), P(4), and P(5). Add those values for your probability.

You can use a binomial probability table, or calculate by hand using the following formula:

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

x = 3,4,5

n = 5

p = 130/680 = 0.19

q = 1 - p = 1 - 0.19 = 0.81

I'll let you take it from here.
