Suppose that 57% of the women who gave birth at a certain hospital last year were over 30 years old, and that 47% were unmarried. If 64% 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 ? Write your answer as a decimal (not as a percentage). (If necessary, consult a list of formulas.) .
