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.

\n" ); document.write( "\"P=0.42%2B0.49\"
\n" ); document.write( "\"P=0.91\"
\n" ); document.write( "We could have also worked it backwards.
\n" ); document.write( "The probability also that at least 1 women purchased plus the probability that neither purchased equals 1.
