Question

A student is waiting to receive mail telling her whether she has been accepted to a certain college. She estimates that the conditional probabilities of receiving notification on each day, given that she is accepted and that she is rejected:
Mon -
P(mail | accept) = .15
P(mail | reject) = .05
Tues -
P(mail | accept) = .2
P(mail | reject) = .1
Wed -
P(mail | accept) = .25
P(mail | reject) = .1
Thurs -
P(mail | accept) = .15
P(mail | reject) = .15

She estimates P(accept) = .6
If there's no mail on Wed, what's the conditional probability that she will be accepted?
