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?

Answer 1

The probability of picking number 2 or 3 is the sum of their individual probabilities:

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

Since each outcome is equally likely, P(2) = P(3) = 1/3:

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

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