An airplane carries 500 passengers 45% are men, 20% are children. The number of women in the airplane is

If we assume the sample space is either men, women, or children to get 100% of the passengers, we have:
PercentWomen = 100% - Men - Children
PercentWomen = 100% - 45% - 20%
PercentWomen = 35%

Calculate Women passengers
Women passengers = Total passengers * Percent Women
Women passengers = 500 * 35%
Women passengers = 175
