#P(odd) = 5/10 = 1/2#

Explanation:

The formula to find a probability is
#p = "number of desirable or wanted outcomes"/"total number of possible outcomes"#

In other words.. "of all the possible ways that an outcome CAN happen, how many do I want?"

IN this example there are 10 given numbers, 5 of them are odd numbers.
So, #P(odd) = 5/10 = 1/2#
