Have you ever tried to get out of jury duty? About 25% of those called will find an excuse (work, poor health, etc.) to avoid jury duty. If 14 people are called for jury duty, a) what is the probability that less than 3 will find an excuse to avoid jury duty? b) What is the probability that exactly 4 will find an excuse to avoid jury duty? c) Find the expected number of those who will find an excuse to avoid jury duty. What is the standard deviation?
