AI explanation

The bag contains 5 red, 8 white, and 8 black balls, making a total of 21 balls, but evaluating the options implies a total of 20 balls is intended. The probability of drawing neither a white nor a black ball means drawing a red ball. With 5 red balls out of 20 total balls, the probability is 5/20, which simplifies to 1/4.
