According to the Census's Population Survey, the percentage of children with two parents at home is the highest for Asians and lowest for blacks (USA TODAY, February 26, 2009). It is reported that $85 \%$ of Asian, $78 \%$ of white, $70 \%$ of Hispanic, and $38 \%$ of black children have two parents at home. Suppose there are 500 students in a representative school, of which 280 are white, 50 are Asian, 100 are Hispanic, and 70 are black.

What is the probability that a child is not white?

Solution

VerifiedIn this exercise, we need to find if the given events are mutually exclusive and exhaustive, the probability of a child not being white, the probability of a child being white and having both parents, and the probability of an Asian child who doesn't have both parents.

The exercise states that the children who have both parents at home are $85\%$ Asian ($P(P|A)=0.85$), $78\%$ white ($P(P|W)=0.78$), $70\%$ Hispanic ($P(P|H)=0.7$), and $38\%$ black ($P(P|B)=0.38$). There are $500$ students, $280$ of them are white, $50$ are Asian, $100$ are Hispanic, and $70$ of them are black.
