You roll a six-sided die twice. What is the probability of rolling a 2 and then an odd number?
the answers are
A. 1/6
B. 1/12
C. 1/2
D. 1/4
The probability of rolling a 2 on the first roll is 1/6. The probability of rolling an odd number (1, 3, or 5) on the second roll is also 1/2. The probability of both of these events happening together is:
1/6 x 1/2 = 1/12
So the answer is B. 1/12.
