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? Write your answer in the simplest form of a fraction.
The probability of picking number 2 or 3 is 2/3.
This is because there are 2 outcomes (2 and 3) out of a total of 3 outcomes in the sample space. So the probability is 2/3.
