Multiple choice

A bag contains $3$ white and $5$ red balls. If a ball is drawn at random, the probability that the drawn ball to be red is:

  1. $\dfrac {3}{8}$
  2. $\dfrac {5}{8}$
  3. $\dfrac {3}{15}$
  4. $\dfrac {5}{15}$

B Correct answer
Explanation

Total balls = 3 (white) + 5 (red) = 8. Probability of drawing a red ball = (Number of red balls) / (Total number of balls) = 5/8.

AI explanation

The total number of balls in the bag is calculated by adding the white and red balls, giving 3 + 5 = 8. The number of favorable outcomes for drawing a red ball is 5. By the definition of classical probability, the likelihood is the number of favorable outcomes divided by the total outcomes, resulting in 5/8.
