Jasmine wants to take BEA111 or BEA140. She knows that for students taking BEA111, the probability that they get an A is 4/5. The probability of getting an A given that the student takes BEA140 is 1/7. If Jasmine makes a random decision on the unit she will take, what is probability of ‘getting an A in BEA140’?
