The probability of one woman making a purchase is equal to the probability of the first purchasing, second not plus the probability of the second purchasing, the first not plus the probability of both purchasing.

We could have also worked it backwards.
The probability also that at least 1 women purchased plus the probability that neither purchased equals 1.
