Please, help me! ( I think my difficulties with it because of my poor English a cause- result? or intersection of 2 events? )
Ann estimates that there is a 60% chance that she will get a raise if she asks her boss.
a) If there is a 40% chance that Ann will, in fact, ask her boss for a raise, what is the probability that she will get a raise because she asked a one?
b) If there is a 10% chance that Ann's boss will give her a raise before she even asks for one, what is the probability that Ann will get a raise without asking for one?
I see that it's about conditional probability, but can't get the answer.
