Question

Which table is a probability distribution table? Responses

1) X 1 2 3 4

P −0.25 0.05 0.35 −0.4



2) X 1 2 3 4

P 0.35, 0.2, 0.25, 0.3



3) X 1 2 3 4

P 0.1, 0.45, 0.3, 0.15



4) X 1 2 3 4

P 0, 0.15, 0.25, 1.2

Answer 1

The table that represents a probability distribution is:

2) X 1 2 3 4

P 0.35, 0.2, 0.25, 0.3

Explanation:

In this table, each value of X (1, 2, 3, 4) has a corresponding probability (P) assigned to it. The probabilities are non-negative and sum up to 1, which is a characteristic of a probability distribution.
