    Suppose 60% of families in a certain town have children. 40% of families have at least one child 6 or under 6, and 60% of families have at least one child over 6. What percentage of families have children of all ages?

    I know I am supposed to use the equation or something like that

    P(a or b) = P(A) + PB) - P(A-B)

    but I am not sure where to put the numbers. Thanks!
