A die is thrown. Find the probability of getting: an even number

Explanation

The sample space has 6 possible outcomes-
S={1,2,3,4,5,6}.

Let all outcomes are equally likely(fair dice).

Hence Probability of any one outcome occurring= 1/6.

The event that we get that an even number on tossing the die can occur in 3 possible ways.

Let E denote this event.
E={2,4,6}

Now `P(E)= 3×1/6​= 1/2`​
