A consumer organization estimates that over a 1-year period 17% of cars will need to be repaired once, 7% will need repairs twice, and 4% will require three or more repairs. If you own 2 cars, what is the probability that
a) neither will need repair?
b) both will need repair?
c) at least one car will need repair?
I'm studying for a test! I understand how you would find the probability for 1 car chosen at random, but not for 2 cars.
Thanks for the help!!
