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
, then
evaluate it using your calculator. (1 point)
B. Using probability notation, P(X = x), write out all the probabilities you'd need to add
up in order to calculate P(X < 6), and then evaluate it using your calculator. (1 point)
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?
