Question

According to a survey, 36.7% of people who visit Disney World have children under 18 in their household. Of these guests with children under 18 in their household, about 15.4% have a total household annual income less than $35,000. Find the probability that a randomly selected Disney World guest has a child under 18 in their household and has a household annual income greater than $35,000.

Expert Solution

Given

A: People who visit Disney World have children under 18 in their household

B: Household with annual income less than $35,000

Therefore,

$\begin{array}{rcl} P (A) & = & 0.367 \\ P (B | A) & = & 0.154 \end{array}$

$\begin{array}{rcl} T o f i n d : P (A \cap B^{c}) \end{array}$
