he sample space of an experiment is S={1,2,3}. Each outcome is equally likely to occur with a probability of 13. What is the probability of picking number 2 or 3? Write your answer in the simplest form of a fraction
The probability of picking number 2 or 3 is the sum of the probabilities of picking each separately. Since each outcome is equally likely, the probability of picking 2 or 3 is:
P(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.
