Question

A 12​-sided die is rolled. The set of equally likely outcomes is ​{1 comma 2 comma 3 comma 4 comma 5 comma 6 comma 7 comma 8 comma 9 comma 10 comma 11 comma 12​}. Find the probability of rolling a number less than 14.

Answer 1

1

Explanation:

Probability is the chance or likelihood that an event will occur.

Probability = Expected number of outcomes/Total outcomes

If a 12sides die is rolled, the sample space is (1,2,3,4,5,6,7,8,9,10,11,12)

The total number of sample space is the total outcome = 12

To find the probability of rolling a number less than 14 means, probability of getting values less than 14. As we can see, the values less than 14 that are in the sample space is also 12(i e all the numbers)

Expected outcome = 12

Probability = 12/12 = 1

This probability is known as a sure event because it is 1

Answer 2

1

Explanation:

It is certain that the number rolled will be less than 14, so the probability is 1.
