Probability Question Help :(

I've been giving a bunch of probability questions to do, and I've been struggling over this one for a while.

Hoping you guys can help me out.

**One in 40 cars of a particular type may develop a fault while under a gaurentee. 12 of these cars are sold. Calculate the probability that:**

(i) 0

(ii) 1

(iii) 2 or more

of these 12 cars will be returned for repair while under gaurentee.

I'd tell you some of the things id treid but they're all completey off the mark.

Any help appreciated.

Thanks in advance.
