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. The results are shown in the table.
