If the probability of obtaining 1 nonconforming unit in a simple of 2 from a large lot of neoprene gaskets is 0.18 and the probability of 2 nonconforming unites 0.25, what is the probability of 0 nonconforming unites?

2. Using the information above, find the probability of obtaining 2 nonconforming unites on the first sample of 2 and 1 nonconforming unites on the second sample of 2. What is the probability of 0 nonconforming using on the first sample and 2 nonconforming unites on the second? The first gasket selected is returned to the lot before the second one is selected?
