Question

# The distribution of a random variable X is given below

The value of k is

Hint:

### We know that, **Sum of all the probabilities in an event = 1. **Use this to find out the answer.

## The correct answer is:

### We know that,

Sum of all the probabilities in an event = 1

P(x= -2) + P(x= -1) + P(x= 0) + P(x= 1) + P(x= 2) + P(x= 3) = 1
