Stuck at a probability question?
If hurricane forms, there is 76% chance it will strike the coast. The probability that the hurricane is formed in an year is 85%.. What is probability that the hurricane will occur and strike coast this year.
I solved it by P(AB) = P(A/B) * P(B).
The problem is solving second part which say of we seed every hurricane formed the probability of striking reduce to 1/4. Now we need to solve first part again.
I am simply dividing the first answer by 1/4 which is giving wrong answer. Any help?
