Question

Two cards are selected at random from 10 each numbered 1 to 10.Find the probability that the sum is odd

Answer 1

Answer:

If you draw one even and one odd, you get an odd sum; otherwise you get an even sum. So the probability of an even sum is 1/4 + 1/4 = 1/2. So the probability of an even sum is 10/45 + 10/45 = 20/45 = 4/9.
