Gregor likes breeding different flowers in his garden. He noticed that when he breeds a white flower with a purple flower, most of the offspring are purple. Let's test the hypothesis that the offspring have equal chances of being either white or purple versus the alternative that the chance of a purple offspring is greater. Assuming the hypothesis is correct, what is the probability of getting a purple offspring?
(a) 25%
(b) 50%
(c) 75%
