According to the 2000 U.S. Census Bureau, 49.65% of Texas residents were male. If one Texan was selected at random in 2000, what is the probability she was female?

The probability that a resident was female is the complement of the probability that a resident was male. Calculate 1 − 0.4965 = 0.5035, or 50.35%. Therefore, the correct choice is 0.5035.
