**CFA Practice Question**

An experiment consists of throwing a die and recording the number of dots on the face of the die facing up. What is the probability that the number of dots is greater than 2 but less than 6?

B. 1/2

C. 1/6

A. 1/3

B. 1/2

C. 1/6

Correct Answer: B

Note that for a fair die, p(X) = 1/6, P(2 < X < 6) = P(X = 3) + P(X = 4) + P(X = 5) = 1/2.

shouldnt the answer be 1/3 because there are 3 possible outcomes between 2 & 6 |

well if there is 3 possible outcomes out of 6, then its 3/6 = 1/2 |
