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 .
(do not round.)

Explanation:

Identify the sample space outcomes

Using the Sample Space Outcomes knowledge point

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

$$ N(S) = 4 $$

Define the event of interest

Using the Classical Probability knowledge point

$$ E = \{RW, WR\} $$

$$ N(E) = 2 $$

Calculate the probability

Using the Classical Probability knowledge point

$$ P(E) = \frac{N(E)}{N(S)} = \frac{2}{4} = 0.5 $$

Answer:

(a) If two pink snapdragons are crossed, the probability that the offspring will be pink is <blank>0.5</blank> (Do not round.)
