If a single fair die is rolled find the probability of a 3 given that the number rolled is odd
a die has 6 sides, there is only one 3, therefore the probability of you getting a is
= 1 in 6
Given that the number rolled is odd, it can be 1, 3, or 5 = 3 possibilities.
Only one of the possibilities is success . . . rolling a 3 .
So the probability of success is 1/3 = 33 and 1/3 percent .
