If two purple snapdragons are crossed, what is the probability that the offspring will be (a) purple, (b) red, and (c) blue? a) If two purple snapdragons are crossed, the probability that the offspring will be purple is Do not round ) (b) If two purple snapdragons are crossed, the probability that the offspring will be red is (Do not round) (C) If two purple snapdragons are crossed,the probability that the offspring will be blue is (Do not round) Enter your answer in each of the answer boxes

Explanation / Answer

(a) There are two choices for the purple offspring i.e BR and RB out of 4.

=> Probability that the offspring will be purple = 2/4 = 0.5.

(b) There is one choice for the red offspring i.e RR out of 4.

=> Probability that the offspring will be red = 1/4 = 0.25.

(c) There is one choice for the blue offspring i.e BB out of 4.

=> Probability that the offspring will be blue = 1/4 = 0.25.
