A consumer organization estimates that over a one-year period: 17% of cars will need to be repaired one time
7% of cars will need to be repaired two times
4% of cars will need to be repaired three or more times

What is the probability that a car chosen at random will need:
no repairs?

no more than one repair? (think of it as one repair or fewer)

some repairs? (think of it as needing one, two, or three repairs)

If you own two cars, what is the probability that:
neither will need to be repaired?

both will need to be repaired?

at least one car will need to be repaired?
