Use the normal approximation to the binomial to find the probabilities for the specific value(s) of X.

Question:

Use the normal approximation to the binomial to find the probabilities for the specific value(s) of X.
a. n = 30, p = 0.5, X = 18
b. n = 50, p = 0.8, X = 44
c. n = 100, p = 0.1, X = 12
d. n = 10, p = 0.5, X ≤ 7
e. n = 20, p = 0.7, X ≥ 12
f. n = 50, p = 0.6, X ≥ 40
