College Debt The following information shows the amount of debt students who graduated from college incur for a specific year.
$$
\begin{array}{cccc}{\$ 1 \text { to }} & {\$ 5001 \text { to }} & {\$ 20,001 \text { to }} & {} \\ {\$ 5000} & {\$ 20,000} & {\$ 50,000} & {\$ 50,000+} \\ {27 \%} & {40 \%} & {19 \%} & {14 \%}\end{array}
$$
If a person who graduates has some debt, find the probability that
$$
\begin{array}{l}{\text { a. It is less than } \$ 5001} \\ {\text { b. It is more than } \$ 20,000} \\ {\text { c. It is between } \$ 1 \text { and } \$ 20,000} \\ {\text { d. It is more than } \$ 50,000}\end{array}
$$
