    Solving Probability: P(S<0), P(S=0), P(S>0)

    Homework Statement let x be a random variable with P(X=-1) = 1/4 P(X=0) = 1/4 P(X=1) = 1/2 Let S be the sum of 25 independant random variables each with the same distribution as X. Calculate approximately a) P(S<0) b) P(S=0) c) P(S>0) Homework Equations Quite possibly the...
