Given a binomial random variable with n = 10 and p = .3, use the formula to find the following probabilities.

a.
P(X = 3) = %28matrix%282%2C1%2C10%2C3%29%29%280.3%5E3%29%280.7%5E7%29 = highlight%280.2668%29

b.
P(X = 5) = %28matrix%282%2C1%2C10%2C5%29%29%280.3%5E5%29%280.7%5E5%29 = highlight%280.1029%29

c.
P(X = 8) = %28matrix%282%2C1%2C10%2C8%29%29%280.3%5E8%29%280.7%5E2%29 = highlight%280.0014%29
