Question
If a die is rolled, then the probability of getting a composite number is_____.
Hint:
We have to find the probability of getting a composite number if a dice is rolled. First we have to find the total number of possible of outcomes which is 6 in this case as if a dice is rolled outcome can only be any number from 1 to 6. Further we will find the number of possible outcomes, we will count total number of composite number from 1 to 6. Then we can easily find the probability by dividing possible outcomes by total number of outcomes.
The correct answer is: 
Total number of outcomes = 2
Total number of outcomes = 6
Probability =
=
So, if a die is rolled, then the probability of getting a composite number is
.
Composite number is the number which has more than two factors.
