Use the random number generator on a graphing calculator. Randomly generate 50 numbers from 0 to 99. The table below shows the results. Let the digits 1 through 6 in the tens place represent rain on Monday. Let digits 1 and 2 in the ones place represent rain on Tuesday. Any number that meets these criteria represents rain on both days. P (rain both days) = 7 50 The experimental probability is 7 50 , 0.14, or 14%. HHH occurred 2 times. There is a total of 20 trials. HTH HTT HTT HTH HTT TTT HHH HTT HTT TTT HTT HTH HTH HHH HTT HTT TTT HTH HTH HTT 7 numbers meet the criteria. There is a total of 50 trials. Study Tip In Example 2, the digits 1 through 6 represent 60% of the possible digits (0 through 9) in the tens place. Likewise, the digits 1 and 2 represent 20% of the possible digits in the ones place.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
