Question

The sample space of an experiment is S={1, 2, 3}. Each outcome is equally likely to occur with a probability of 1/3. What is the probability of picking number 2 or 3?

Answer 1

Since the outcomes are equally likely, we can calculate the probability of picking number 2 or 3 by adding the individual probabilities of picking each number.

P(picking number 2 or 3) = P(2) + P(3) = 1/3 + 1/3 = 2/3

Therefore, the probability of picking number 2 or 3 is 2/3.
