Question

when two pink flowers (rw) are crossed, there are four equally likely possible outcomes for the genetic makeup of the offspring: red (rr), pink(rw), pink(wr), and white (ww). if two pink snapdragons are crossed, what is the probability that the offspring will be (a) pink, (b) red, and (c) white?

(a) if two pink snapdragons are crossed, the probability that the offspring will be pink is 0.5.
(do not round.)

(b) if two pink snapdragons are crossed, the probability that the offspring will be red is 0.25.
(do not round.)

(c) if two pink snapdragons are crossed, the probability that the offspring will be white is
(do not round.)

Explanation:

Define the sample space

Using the Sample Space Outcomes knowledge point

$$ S = \{\text{RR}, \text{RW}, \text{WR}, \text{WW}\} $$

$$ N(S) = 4 $$

Calculate the probability of pink offspring
