Question

If a die is rolled, find the probability of rolling an even number

Answer 1

First write the S of the scenario. A die has 6 possible numbers.
S = {1,2,3,4,5,6}
E in this scenario is all possible even numbers.
E = {2,4,6}
Then write the classical probability.
P(E) = n(E) / n(S) = 3 / 6 = 1 / 2
