1. A standard six-sided die is rolled. What is the probability that the number rolled is greater than or equal to 3, given you know the number is odd?
A. 1/3
B. 2/3
C. 1/2
D. 1/6
B. 2/3
There are 3 odd numbers on a standard six-sided die: 1, 3, 5. Out of these 3 odd numbers, only 2 of them (3 and 5) are greater than or equal to 3. Therefore, the probability of rolling a number greater than or equal to 3 given that the number is odd is 2/3.
