Interpret the probability distribution of the number of heads when flipping two fair coins.

• P(0 heads) = 1/2, P(1 head) = 1/4, P(2 heads) = 1/4

• P(0 heads) = 1/2, P(1 head) = 1/2, P(2 heads) = 0

• P(0 heads) = 1/4, P(1 head) = 1/2, P(2 heads) = 1/4

• P(0 heads) = 1/3, P(1 head) = 1/3, P(2 heads) = 1/3
