For any problem like this you want to list the full set of possibilities, in this case: {1,2,3,4,5,6}. Then list the desired elements that form the subset of values your question requires, in this case: the odd numbers {1,3,5}. Count ’em up, and divide the subset count by the total count:
Prob(value in subset)=Number of Elements in SubsetTotal Number of Elements
In this case we have 3 odd numbers (size of the subset is 3) and 6 numbers in total (total number of elements is 6):

In this case we have 3 odd numbers (size of the subset is 3) and 6 numbers in total (total number of elements is 6):
Prob( odd number on a 6-sided die )=3/6=1/2
