A bag contains 5 red balls and 3 blue balls. If two balls are drawn at random without replacement, what is the probability that both balls are red?

A 5/14
B 1/4
C 9/28
D 25/64

✓ Correct Answer: Option A

The probability of drawing the first red ball is 5/8. After one red ball is drawn, there are 4 red balls left out of 7 total. The probability of drawing a second red ball is 4/7. The combined probability is (5/8) * (4/7) = 20/56 = 5/14.
