Final answer:
To create a legitimate probability distribution for a discrete random variable X, assign probabilities to the possible values of X such that the probabilities are non-negative and their sum is equal to 1.
Step-by-step explanation:
A legitimate probability distribution for a discrete random variable X must assign probabilities to the possible values. In this case, the possible values of X are 1, 3, 4, 5, and 6.
To satisfy the conditions of a legitimate probability distribution, the probabilities must be non-negative and the sum of all probabilities must equal 1.
Let's fill in the probabilities for each value of X:
P(X=1) = **1/6**
P(X=3) = **1/6**
P(X=4) = **1/6**
P(X=5) = **2/6**
P(X=6) = **1/6**
