On average, out of 500 garden pumps on sale, 4 are leaking. Find the likelihood that one randomly selected control pump does not leak

1) 500 – 4 = 496 pumps do not leak.
The number of favorable outcomes is 496 (no leaking pumps).
The number of all possible outcomes is 500 (all pumps).
We find probability as the ratio of favorable outcomes of experiment 496 to the number of all possible outcomes 500.
2) 496/500 = 0.992
