Answer

Explanation:

Step1: Check probability - distribution requirements

  1. The probabilities (P(x)): (0.0363), (0.3037), (0.060) are all between (0) and (1) inclusive.
  2. Calculate the sum of probabilities: (0.0363 + 0.3037+0.060=0.4\neq1).
  3. The random - variable (x) (left, right, no preference) is categorical. A probability distribution requires a numerical random variable.

Step2: Determine if it's a probability distribution

Since the random variable (x) is categorical instead of numerical and the sum of probabilities is not equal to (1), it is not a probability distribution.

Answer:

B. No, the random variable x is categorical instead of numerical D. No, the sum of all the probabilities is not equal to 1 B. The table does not show a probability distribution B. The table does not show a probability distribution
