There is a 75% chance that a random company will meet its earnings expectations in a random quarter. If we take a random sample of 4 companies, what is the probability that exactly 3 of the companies meet their earnings expectations in that quarter?

But the “by hand” calculation is easy and discussed in our chapter.)

The probability that a randomly selected company will file a revised 10-k next year is 10%. If we take a random sample of 6 companies, what is the expected number of companies that will file a revised 10-k next year?
