Question

Determine the required value of the missing probability to make the distribution a discrete probability distribution

P(4)=____

X       P(x)

3      0.25

4      ?

5      0.39

6      0.15

Answer 1

Concepts and reason

A discrete probability distribution for the discrete random variable lists each possible value the variable can assume, together with its probability.

Fundamentals

A table, formula that lists all possible values a discrete random variable can assume together with associated probabilities.

The total probability is always equal to 1.

The given probability table is,

Ans:

The missing probability value is, 0.21.
