Question

You roll a die numbered from 1 to 6. What is the probability that the sum is not 6?

Answer 1

If you are throwing 1 die then the probability is 5/6 or 83.3% but if you are rolling 2 die then the probability is 25/36 or 69.4%

Answer 2

Answer:2/3 or approximately 0.667.

Explanation:

total number of outcomes =6

We can obtain a sum of 6: rolling a 1 and a 5, or rolling a 2 and a 4.

Therefore, the number of outcomes that do not result in a sum of 6 is:

6 - 2 = 4

So the probability of getting a sum that is not 6 is:

P(sum is not 6) = number of outcomes that do not result in a sum of 6 / total number of possible outcomes

P(sum is not 6) = 4 / 6

P(sum is not 6) = 2 / 3
