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

`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`
