A box contains one yellow, two red, and three green balls. Two balls are randomly chosen without replacement. Define the following events, and use them to find the conditional probabilities below.
A:{A:{ One of the balls is yellow }}
B:{B:{ At least one ball is red }}
C:{C:{ Both balls are green }}
D:{D:{ Both balls are of the same color }}
a) P(B¯¯¯¯|A)=
b) P(B¯¯¯¯|D)=
c) P(C|D)=
Suppose that E and F are events in the sample space with
P(E∩F)=0.03, P(E|F)=0.1, and P(F|E)=0.2. Find the following
probabilities.
a) P(E)=
b) P(F)=
c) P(E∪F)=
