Question

A bag contains 24 balls of which 4 are red, 8 are white and remaining are blue. A ball is drawn at random, the probability of it to be blue is:

विकल्प

• 0·5

• 1

• \[\frac{1}{3}\]

• 2

Answer 1

0·5

Explanation:

No. of blue balls = 24 − 4 − 8 = 12

P(drawing a blue ball)

\[{} = \frac{\text{No. of favourable outcomes}}{\text{Total no. of possible outcomes}} = \frac{12}{24} = \frac{1}{2} = 0.5\]
