Let X1, . . . , X30 be independent random variables each having a discrete distribution with p.f.
Let X1, . . . , X30 be independent random

Use the central limit theorem and the correction for continuity to approximate the probability that X1 + . . . + X30 is at most 33.

f x = 0 or 2. if x=1, 1/4 f(x)=11/2 0 otherwise.
