d. You go bowling with your daughter. She is a pretty good bowler and you calculate the probability of her knocking down pins in her turn as follows

# Pins	Probability
10	.10
9	.40
8	.40
7	.10

Calculate the expected number of pins you expect her to knock down in a turn.

Calculate the standard deviation of the expected number of pins you expect her to knock down
