\n" ); document.write( "If 61% of the women were over 30 or unmarried (or both), what is the probability that a woman who gave birth at the hospital was both unmarried and over 30 ?
\n" ); document.write( "----------------------------------------------
\n" ); document.write( "P(>30 and unmarried) = P(>30) + P(unmarried) - P(>30 or unmarried)
\n" ); document.write( "= 0.51 + 0.51 - 0.61
