Suppose we choose 2 integers from 1, 2, 3, ..., 9. What is the probability that they are both odd?
+781 The odd integers in this set are 1, 3, 5, 7, and 9.
The probability of the first integer being odd is 5/9.
The probability of the second integer being odd is 4/8=1/2.
So the probability they are both odd is 5/9 * 1/2= 5/18.
