An experiment consists of inspecting fuses as they come off

An experiment consists of inspecting fuses as they come off a production line until the first defective fuse is found. Assume that each fuse is defective with a probability of 0.01, independently of other fuses. Find the probability that a total of eight fuses are inspected.

P(first seven are okay, 8th is defective) = (1-0.01)^7 * 0.01 = 0.009320653 [ANSWER]
