Use the binomial probability formula:
P(X = k) = C(n,k) * p^k * q^(nk)
n : number of trials (5)
k : number of desired outcomes (0, 1, 2, ..., 5)
p : probability of that outcome (0.08)
q : probability of the opposite outcome (1p = 0.92)
Now just create a probability histogram.
P(X=0) = C(5,0) * 0.08^0 * 0.92^5 = 0.6590815232
P(X=1) = C(5,1) * 0.08^1 * 0.92^4 = 0.286557184
P(X=2) = C(5,2) * 0.08^2 * 0.92^3 = 0.049836032
P(X=3) = C(5,3) * 0.08^3 * 0.92^2 = ...
P(X=4) = C(5,4) * 0.08^4 * 0.92^1 = ...
P(X=5) = C(5,5) * 0.08^5 * 0.92^0 = ...
For the expected number of chips, compute the Expected Value.
E(X) = 0 * P(X=0) + 1 * P(X=1) + 2 * P(X=2) + 3 * P(X=3) + 4 * P(X=4) + 5 * P(X=5)
