macOS Boolean Algebra

Seems like homework. The first reduces to the second. The second seems done to me.

can someone please help simplify the below two Boolean Algebra expressions.

Y=(AB)+(~AC)+(BC)

Z= (AB)+(~AC)

Take the first one, and then express it in words. Please post the result - feedback is very much appreciated. ("Thank you for your help" is no feedback). While lee's answer is completely correct, when I did homework it wouldn't have been accepted (because there is no evidence how you got to the answer).

If AB isn't true, and ~A isn't true, what can you say about B and why?
