Question

A​ 12-sided solid has faces numbered 1 through 12. a. Find the probability of rolling a number greater than 5. b. If the​ 12-sided solid is rolled 180​ times, how many times would you expect either a​ 3, 9, or 11 to be​ rolled? Question content area bottom Part 1 a. The probability of rolling a number greater than 5 is

Answer 1

1) first one is 7/12

the second one is 45

as the chance of getting a 3,9 or 11 is 3/12

So you do 3/12 x 180 = 540/12 which is simplified to 45.
