Mr. Smith can drive to work along the shortest path or bypass.

He drives the shortest path in 36% cases. The probabilty he will get stuck in traffic jam

on the shortest road is 20%, in addition in the case of traffic jam he can miss the work with the probability of 10%.

The probability to get stuck in traffic on bypass road is 8%, in addition after getting out of traffic jam, he can

miss work with the probability of 24%.

a) what is the probability, Mr. Smith will miss the work?

b) If Mr. Smith misses work, what is the probability, he was driving bypass road?

Do I have to use full probability, Bayse formula or something else?
