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)
$$
The probability of picking number 2 or 3 can be calculated by adding the individual probabilities of picking 2 and picking 3, since they are mutually exclusive events.
Probability of picking 2 = 1/3
Probability of picking 3 = 1/3
Probability of picking 2 or 3 = Probability of picking 2 + Probability of picking 3
= 1/3 + 1/3
= 2/3
Therefore, the probability of picking number 2 or 3 is 2/3.
