4.The advertising director for a television show has 7 ads to use on the program. If she selects one of them for the opening of the show, one for the middle of the show, and one for the end of the show, how many possible ways can this be accomplished?

5. (5 points) There are 12 boys and 14 girls in a math class.Find the number of ways one can select a team of 3 students from the class to work on a group project. The team is to consist of 2 girls and 1 boy.

6. (5 points) It is believed that 60% of Americans have health insurance.Suppose X represents the number with no health insurance in a random sample of 15 Americans.Determine the probability of exactly two Americans with no health insurance.

7. (5 points) Suppose it is known that a mathematics textbook has, on average, 2.1 misprints. What is the probability that in a given page there are 5 misprints?

(answer 8 as well !!!)
