Question

A bag contains 4 red and 6 black balls. A ball is taken out of the bag at random. What is the probability of getting a black ball?

Options

• `2/5`

• `3/5`

• `1/10`

• None of these

Answer 1

`bb(3/5)`

Explanation:

Total possible outcomes = Total number of balls

= (4 + 6)

= 10

Number of black balls = 6

∴ P(getting a black ball) = `6/10 = 3/5`.
