Multiple choice

A bag contains $3$ white and $5$ black balls. One ball is drawn at random. Then the probability that it is white is:

  1. $\displaystyle \frac { 1 }{ 8 } $
  2. $\displaystyle \frac { 3 }{ 8 } $
  3. $\displaystyle \frac { 5 }{ 8 } $
  4. $\displaystyle \frac { 3 }{ 5 } $

B Correct answer
Explanation

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

AI explanation

The total number of balls is 3 white + 5 black = 8 balls. According to the classical definition of probability, the probability of drawing a white ball is the number of white balls divided by the total number of balls. Therefore, the required probability is 3 divided by 8, which is 3/8.
