Larry reads that one out of four eggs contains salmonella bacteria. So he never uses more than three eggs in cooking. If eggs do or don’t contain salmonella independent of each other, the number of contaminated eggs when Larry uses three chosen at random has the distribution
a. binomial with n = 4 and p = 1/4.
b. binomial with n = 3 and p = 1/4.
c. binomial with n = 3 and p = 1/3.

random variable X as the number of defective cameras in the
sample.

The default rate on government-guaranteed student loans at a certain public four-year institution is 8 percent and 1,000 student loans are made at the institution. If we assume that the defaults are statistically independent across loans, the number of total defaults at the institution is a binomial random variable. However, we will approximate the binomial distribution by the standard normal distribution using the central limit theorem. Calculate the probability of 65 or fewer defaults using the central limit theorem. a....
