Answer:
P(X=0) = 0.25
P(X=1) = 0.50
P(X=2) = 0.25
Step-by-step explanation:
The possible outcomes of this event are: BB, BG, GB and GG.
There is one out of four events (GG) in which there are two girls (X=2).
There is one out of four events (BB) in which there are no girls(X=0).
There are two out of four events (GB and BG)) in which there is one girl (X=1).
Therefore, the probability distribution of X is:
P(X=0) = 1/4 = 0.25
P(X=1) = 2/4 = 0.50
P(X=2) = 1/4 = 0.25
