Question

If a fair die is rolled four times, which of the following is closest to the probability that at least one

roll will show the number 4?*
1) 17%
2) 67%
3) 52%
4) 36%​

Answer 1

Answer is 67%

Explanation:

If you want to get the number four from 4 rolls the chances would be

1st roll = 1/6 (16.667%)

2nd roll = 2/6 (33.333%)

3rd roll = 3/6 (50.000%)

4th roll = 4/6 (66.667%)

So the answer is 67%
