Q:

Joanie rolls two 1-6 number cubes 80 times. is it likely she will roll a sum of 5 more than 12 times?F yes,because the probability of rolling a sum of 5 is 1/6 and 1/6×80=13 1/3 which is more than 12.G. yes, because the probability of rolling a sum of 5 is 1/4 and 1/4×80=20 which is more than 12.H. no, because the probability of rolling a sum of 5 is 1/10 and 1/10×80=8 which is less than 12.J. no, because the probability of rolling a sum of 5 is 1/9 and 1/9×80=8 8/9 which is less than 12.

Accepted Solution

A:
the answer is j. no, because the probability of rolling a sum of 5 is is 1/9 and 1/9*80=8 8/9 which is less than 12.
