Question: two dice are thrown simultaneously what is the probability of getting a doublet?
Answer: To get a even doublet, you have only three possibilities (2,2), (4,4) and (6,6) out of a total of 36. Since all 36 possibilities are equally likely the chance of a even doublet is 3/36 = 1/12. ... If you throw two dice, what is the probability of getting a multiple of 3 (sum of the two)?
