In this situation, rolling a six-sided has 6 outcomes, each of which is equally likely, so we can define the probability of an event (such as rolling a 3 or rolling an odd number) as the ratio of favorable outcomes to possible outcomes: the probability of rolling a 3 is 16 and the probability of rolling an odd number
If we are talking about a six-sided die, there are only six outcomes: 1, 2, 3, 4, 5, 6. The only odd number outcomes are 1, 3, 5. To find the probability, we divide the number of desired outcomes by the total number of outcomes.
