How do you calculate the probability of rolling an even number on a die?

Back

There are 3 even numbers (2, 4, 6) on a die. P(even) = Number of even outcomes / Total outcomes = 3/6 = 1/2.

What is the probability of rolling a number greater than 4 on a die?

Back

There are 2 outcomes (5, 6) that are greater than 4. P(greater than 4) = 2/6 = 1/3.
