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?

✓ Correct Answer: Option C

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