Q:
# 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 and divide by the number of trials. This gives an estimated probability of about . 20 pts for the first one to answer and if it is correct you get brainiest answer

A:

Answer:The estimated probability is about:0.1333=13.33%Step-by-step explanation:It is given 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.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. The results of 15 trials are given as:561673 366468 314255 361362 838443 126285 257231 768551 652585 468113 123711 322764 487626 783134 384664So, the number of trials that have two or more 1 in it will represent the trial that 2 or more out of 6 packs will have an all-star card.Number of trials that represent that 2 or more out of 6 packs have an all-star are:2( Since, the trials are: 468113 and 123711 )Hence, the estimated probability that 2 or more out of 6 have an all-star is:2/15=0.13333=13.33%
