1.Suppose I pick (without looking) a jelly bean from a box containingfourred beans and seven blue beans. I record the color and put the bean back in the box. Then I choose a bean again.

What is the probability of getting a blue bean both times? (Enter your probability as a fraction.)

2.he city finds empirically that the probability that an automobile going through the intersection of 5th and Main will run a red light sometime during a given day is8.9%, and the probability that an automobile going through the intersection of 7th and Polk will run a red light sometime during a given day is 11.7%. Suppose a car is picked at random at 5th and Main on a given day and another at random at 7th and Polk. Write each probability as a percentage rounded to one decimal place.

What is the probability that the car will not run a red light at 5th and Main?

%

What is the probability that the car will not run a red light at 7th and Polk?

%

What is the probability that neither car runs a red light?
