A manufacturer makes lightbulbs and claims that their reliability is 98 percent. Reliability is defined to be the proportion of the non-defective items that are produced over the long term. If the company’s claim is correct, what is the expected number of non-defective lightbulbs in a random sample of 1,000 bulbs?

Joe and Matthew plan to visit a bookstore. Based on their previous visits to this bookstore, the probability distributions of the number of books they will buy are given below: Number of books Joe will buy 0 1 2 Probability 0.50 0.25 0.25 Number of books Matthew will buy 0 1 2 Probability 0.25 0.50 0.25 Assuming that Joe and Matthew make their decisions independently, what is the probability that they will purchase no books on this visit to the bookstore?

A complex electronic device contains three components, A, B, and C. The probabilities of failure for each component in any one year are: 0.01, 0.03, 0.04, respectively. If any one component fails, the device will fail. If the components fail independently of one another, what is the probability that the device will not fail in one year?
