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

Answer 1

Since each outcome is equally likely to occur, the probability of picking number 2 and number 3 are both 1/3. Therefore, the probability of picking number 2 or number 3 is the sum of their individual probabilities:

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

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