    There is a 50% probability that a randomly selected family has an income greater than $57,800

    Step-by-step explanation:

    The median separates the upper half from the lower half of a set. So 50% of the values in a data set lie at or below the median, and 50% lie at or above the median.

    In this problem, we have that:

    Median is $57,800.

    So 50% of the families have incomes higher than $57,800 and 50% of the families have incomes lower than $57,800.

    There is a 50% probability that a randomly selected family has an income greater than $57,800
