Answer:

C The probability values do not add to 1

Step-by-step explanation:

Given

The above table

Required

Why is it not a probability distribution

In probability, the sum of all probabilities must equal 0.

But in this case:

[tex]\sum P(x) \ne 0[/tex]

Because:

[tex]0.08 + 0.23 + 0.44 + 0.12 + 0.24 \ne 0[/tex]

[tex]1.11 \ne 0[/tex]

Hence:
