Chapter 13.2, Problem 25E

Part-time work and time to graduate. The following (hypothetical) table shows the relationship between the number of hours students work at part-time jobs each week and the number of years it takes then graduate with an undergraduate degree. Use the data in this table to do Exercises 25–28. Express your answers correct to three decimal places.

Amount of Hours Worked per Week	4 years	5–6 years	Over 6 years	Totals
0–2	172	72	24	268
6–20	120	96	32	248
Over 20	68	132	44	244
Totals	360	300	100	760

If a student works more than 20 hours per week, what is the probability that the student graduates in 4 years?
