Question

When Mendel experimented with crossing different types of peas, he noted both the color (green or yellow) and the shape (round or wrinkled) of the peas produced. The table below gives the predicted percentage of each type according to Mendelian genetics.

Round 0.1875 (green) 0.5625 (yellow)

Wrinkled 0.0625(green) 0.1875(yellow)

If one pea is drawn at random from the peas produced, what is the probability it is round?

If a simple random sample of 20 peas is drawn from those produced, what is the expected number of round peas?

If a simple random sample of 20 peas is drawn from those produced, what is the standard deviation of the number of round peas? (Round your answer to two decimal places.)
