1.2 is the answer to your question.
D
The domain is the x values, so the right side of the circle are the x’s.
P(all 4 are male) = 1/2^4 = 1/16 ( assuming probability of 1 male = 1/2)
P( 3 are male) = 1/2^4*4 = 1/4
The rest will have at least 2 females
So probability of at least 2 females) = 1 - 1/16 - 1/4 = 1 - 5/16 = 11/16 answer
It would come out to 240/50 which would equal 4.8
plus 0.5 which would equal 5.3 so d is your answer
