Final answer:
To find the probability that X is 2 or 3, we add the probabilities for X = 2 and X = 3 from the discrete probability density function provided in the question.
Step-by-step explanation:
The student is asking about the probability of a discrete random variable, which in this context is the chance that the variable X takes on the values of either 2 or 3. Given the probability density function (PDF), we determine these probabilities by adding the individual probabilities of X being 2 or 3 together.
Based on the information provided, we extract the probabilities for X = 2 and X = 3 from the PDF table. The sum of these two probabilities gives us P(X = 2 or X = 3), which is the answer we seek. It's important to remember that since it's a discrete PDF, the probabilities must sum to one, and each individual probability must be between 0 and 1.
