Question

A bag has 6 balls; two of each color red, blue, green. What is the probability of picking a red ball from bag?

(a) \(\frac{1}{2}\)

(b) \(\frac{1}{3}\)

(c) \(\frac{1}{4}\)

(d) \(\frac{1}{6}\)

I have been asked this question at a job interview.

This intriguing question comes from Data Handling in section Data Handling of Mathematics – Class 8

Answer 1

The correct option is (b) \(\frac{1}{3}\)

For explanation I would say: A bag has 6 balls; two of each color red, blue, green. When a ball is picked from bag, it can be of red, blue or green. So possible outcome of picking ball from bag is 3. Hence, the probability of picking a red ball from the bag is \(\frac{1}{3}\).
