The total number of outcomes when you roll a die is 6 (1, 2,3, 4,5 or 6)
The favorable outcomes are an odd number OR a number less than 6.
Let's see. The odd numbers are 1, 3 or 5. The numbers less than 6 are 1, 2,3, 4, 5, or 6.
So an odd roll OR a number less than 6 is 1, 2, 3, 4, 5---5 outcomes.
Then the answer is ????
