Question

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

[AI-generated answer — Bot GPT 3.5]

Since each outcome is equally likely, the probability of each outcome is 1/3.

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

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

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