In a valid probability distribution, each probability must be between 0 and 1,inclusive, and the probabilities must add up to 1. If a probability distribution5has probabilities1,112, and x, what is the value of X?

Given:

The probability distribution is given by,

To find:

The value of x.

Explanation:

We know that,

The probabilities must add up to 1.

So, we write

Solving for x we get

Therefore, the value of x is,

Final Option D

The value of x is,

entering that problem on the tube might get you an answer

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
