Answer:

Explanation:
Given an event A
The probability of A occurring + The probability of A not occurring=1
or we can say:
P(A)+P(
)=1, where
is the complement of A.
In the given problem, if the probability of selecting a pink rose is 1/4.
(I want to presume its 1/4 not 14 since probability cannot be greater than 1)
We then have:
P(selecting a pink rose) + P(not selecting a pink rose)=1
P(not selecting a pink rose)=1-P(selecting a pink rose)
