The 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.(1 point)
Since each outcome is equally likely, the probability of picking number 2 or 3 is the sum of the individual probabilities of picking 2 and picking 3.
P(2) = 1/3
P(3) = 1/3
Therefore, P(2 or 3) = P(2) + P(3)
= 1/3 + 1/3
= 2/3
So, the probability of picking number 2 or 3 is 2/3.
