When buying a candy bar, there is a 20% chance that it will also include a coupon for a second candy bar. a student
wants to determine the probability that, if she buys 7 candy bars, more than 2 will include a coupon.

to do this, she uses a random number table to pick 7 numbers from 1 to 5. she lets 1 represent a candy bar with a
coupon and numbers 2 through 5 represent a candy bar without a coupon.. she repeats this for a total of 16 trials. theresults are shown in the table.
5144543 2114445 2113415 4341112

1455141 4554414 5154443 3153242

select from the drop-down menus to correctly complete each statement

to estimate the probability that more than 2 out of 7 candy bars will include a coupon, the student must count the numberof trials with choose and divide by the number of trials.

this gives an estimated probability of about choose
