In this problem, it is said that a 12 -sided die is rolled.
00:04
So the set of equally likely outcomes is the set containing the elements 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12.
00:14
We need to find the probability of rolling a number greater than 15.
00:19
Now, the required probability will be the number of favorable outcomes divided by the total number of outcomes.
00:25
First of all, consider the total number of outcomes, which we write in the denominator here.
00:29
Now the total number of outcomes will be 12 because that is the number of elements in the given set of equally likely outcomes.
00:38
It is a 12 -sided die.
00:39
There are 12 outcomes possible and so the total number of outcomes is 12.
00:44
Next consider the number of favorable outcomes which you write in the numerator here...
