A company says that the probability of finding an all-star card in a game pack is 12.5%. A student wants to determine the probability that, if he buys 6 game packs, 2 or more will have an all-star card. To do this, he uses a random number table to pick 6 numbers from 1 to 8. He lets 1 represent a pack with an all-star card and 2 through 8 represent a pack without an all-star card. He repeats this for a total of 15 trials. The results are shown in the table. 561673 366468 314255 361362 838443 126285 257231 768551 652585 468113 123711 322764 487626 783134 384664 Select from the drop-down menus to correctly complete each statement. To estimate the probability that 2 or more out of 6 packs will have an all-star card, the student must count the number of trials with BOX RIGHT HERE and divide by the number of trials. This gives an estimated probability of about . BOX RIGHT HEREPLEASE I NEED THIS ANSWERED I HOPE ITS CLEAR ENOUGH.
