1. Let X be a binomial random variable with n = 20 and p = .3. A. Write the expression for P(X = 6)

1. Let X be a binomial random variable with n = 20 and p = .3. A. Write the expression for P(X = 6) in terms of the formula (n/x)(p)^x (1-p)^n-x , then evaluate it using your calculator.

B. Using probability notation, P(X = x), write out all the probabilities you'd need to add up in order to calculate P(X

C. For part B, why did you choose the upper bound that you did? If you were using the normal approximation could you choose a different upper bound? Why or why not?
