The 4-sided die, labeled 1–4, is rolled twice.
What is the probability of rolling two 3s?
a 6.25%
b 12.5%
c 25%
d 50%
b) 12.5%
There are a total of 4^2 = 16 possible outcomes when rolling a 4-sided die twice. Out of those, only one outcome results in rolling two 3s. So the probability is 1/16 = 0.125 = 12.5%.
