A box contains one yellow, two red, and three green balls. Two balls are randomly chosen without replacement. Define the following events:
These are the values I have come up with that I think are right, I also think I have managed to answer 2 of the questions but am really struggling with the rest.
A: One of the balls is yellow (1/3)
B: At least one ball is red (3/5)
C: Both balls are green (1/5)
D: Both balls are of the same color (4/15)
a) P(not A|B) = ?
b) P(B|not D) = ?
c) P(Ac|B) = ?
d) P(Bc|D) = ?
e) P(C|D) = 3/4
f) P(D|C)= 1
Thanks so much!
