Question

A bag contains 6 red, 5 black and 4 white balls. A ball is drawn from the bag at random. Find the probability that the ball drawn is white.

Answer 1

Given: A bag contains 6 red, 5 black and 4 white balls.

Step-wise calculation:

1. Total number of balls

= 6 + 5 + 4

= 15

2. Number of favourable outcomes (white balls) = 4.

3. Probability (white) = `"Favourable"/"Total"`

= `4/15`

The probability that the ball drawn is white is `4/15` (≈ 0.2667).
