a) Consider two workshops, A and B. A is a woodworking shop with a probability of fire, of 0.05. B is a metal workshop, where the probability is 0.02. The buildings are so close together that I one catches fire, there is an 55% chance (85%) that the other will burn as well. Determine the probability if A starts the fire and spreads it to E. probability (A

and B)

E is way down the street, so it's safe.
