First, decide whether the distribution is a discrete probability distribution, then select the reason for making this decision.
Lyrx [107]

It is not a <u>probability distribution</u>, as the sum of the probabilities is more than 1, thus, the correct option is No, considering that:

c) Since the sum of the probabilities is not equal to 1.

-----------------------------------------

For the sequence (x, P(X = x)) representing a probability distribution, it is needed that:

  • All probabilities are between 0 and 1, that is, for all values of x, 0 \leq P(X = x) \leq 1.
  • The sum of all probabilities is 1, that is: \sum_{i = 1}^n P(x_i) = 1

In this problem, the sum of the probabilities is:

\sum_{i = 1}^n P(x_i) = 0.39 + 0.69 + 0.12 = 1.20

<u>Sum is not 1,</u> thus it is not a probability distribution, and the correct option is:

c) Since the sum of the probabilities is not equal to 1.
