Since all probabilities must sum to 1,

we can easily see that since the probability of having a pure white guinea pig is 0.25

the probability of NOT having a pure white guinea pig is 1-0.25 or 0.75

This is also known as finding the complement of an event.

The event is a pure white offspring with p=0.25

The complement of that event is NOT having a pure white offspring with p=0.75

I hope this helps!
