Ten percent of cereal boxes have a prize. A student wants to estimate the probability that when 8 boxes are purchased, fewer than 3 have a prize.

To do this, the student uses a random number table to pick 8 numbers from 0 to 9. She lets 0 represent a box with a prize and 1 through 9 represent a box without a prize. She repeats this for a total of 12 trials. The results are shown in the table.

Select from the drop-down menus to correctly complete each statement.

To estimate the probability that fewer than 3 out of 8 boxes have a prize, the student must count the number of trials with and divide by the number of trials.

This gives an estimated probability of about.
