Question

If a fair die is rolled 7 times, what is the probability, to the nearest thousandth, of getting exactly 5 threes?

Answer 1

0.119

Explanation:

No. of sides a die has= 6 sides

No. of times it is rolled= 7 times

Total pairs= 6 x 7

= 42 pairs

No. of 5 threes= 5 x 1

= 5

Probability of getting 5 threes= Favorable outcomes/Total outcome

=
`(5)/(42)`

= 0.119 chance

∴ probability of getting 5 threes is 0.119
