Question

Find the probability of not rolling factors of 5 on both dice

Answer 1

Answer:

What's the probability of not rolling factors of 2 on both dice?

For two dice Total possible outcome is= 36.

and factors of 2 = 1 & 2.

Probability of getting factors of 2 on 1st dice = 26=13

Similarly for 2nd dice , Probability is 13

Since, both events are equally likely events.

Both , events are independent .

So, Probability of getting factors of 2 on both dice = 13×13=19

Therefore, probability of not getting factors of 2 on both dice = 1 - 19=89.
