Use the Probability Formula.
1/3
When calculating probability, we are comparing the number of favorable outcomes to the number of possible outcomes. To calculate the probability that a multiple of 3 is rolled on a 6-sided die, we will use the Probability Formula.
Substitute values
a/b=.a /2./.b /2.
The probability of rolling a multiple of 3 is 13, which can also be written as 1:3.
