Laura has applied for a job with Apple As part of the hiring

Laura has applied for a job with Apple. As part of the hiring process, Apple will of course look at her grade in BUS 90 at SJSU. If Laura gets an A, there is a 75% chance that Apple will hire her. But if she does not get an A, there is only a 10% chance that they will hire her. Laura\'s professor says that there is a 70% chance that Laura will get an A in BUS 90.

What is the probability that Laura gets an A in BUS 90 and also gets hired by Facebook?

Solution

Probability that Laura will get A grade = 70/100 and probability of getting selected 90/100 if she gets A

Now the probability that she will be selected and will get A Grade will be =70*90/10000=6300/10000 =0.63

So the correct option will be D.
