Answer

Explanation:

Step1: Check requirements for probability distribution

A probability distribution has a random - variable (x) which is numerical and the sum of all probabilities (P(x)) must be 1, and each (P(x)) must be between 0 and 1 inclusive. Here, the random variable (x) (left, right, no preference) is categorical.

Step2: Analyze sum of probabilities

(0.6354 + 0.3043+0.0596=0.9993\neq1)

Answer:

B. No, the random variable x is categorical instead of numerical C. No, the sum of all the probabilities is not equal to 1
