There is a .97 chance that no accident will occur during any particular day at a racetrack of local importance. the probability of one accident a day is .02, and the probability of two accidents is .01.

a. What is the expected number of accidents in a day?

b. What is the expected number of accidents in ten days?

I just don't understand how to set these questions up and any help would be much appreciated.
