Question

Please help!
The first outcome is one of (A,B,C) and the second outcome in each case is one of (1,2)...
Pr[A] = [ 1/3], Pr[A1] = [ 1/4], Pr[A2] = [ 1/12], Pr[1|B] = [ 1/2], Pr[2|B] = [ 1/2], Pr[B1] = [ 1/6], Pr[B2] = [ 1/6], Pr[C1] = [ 1/12], Pr[C2] = [ 1/4]

What is Pr[1|A], Pr[C], and Pr[2|C]?

I am very lost.

Answer 1

I'm not sure what these Pr[2|B] types come in though
