Easy
A fair die is rolled once. What is the probability of getting an odd number?
Explanation
Explanation
A die has 6 equally likely outcomes: 1, 2, 3, 4, 5, 6. The favourable outcomes for 'an odd number' are [1, 3, 5], which is 3 outcomes. So P = (favourable outcomes)/(total outcomes) = 3/6.
PRO TIP
Re-check your working by substituting the answer back into the original question.
