The answers, and why
- How many faces does an ordinary die have? Six. An ordinary die is a cube with six faces, numbered 1 to 6.
- On a normal die, opposite faces always add up to... Seven. 1 is opposite 6, 2 opposite 5 and 3 opposite 4: each pair makes 7.
- How many dots are on a die altogether? 21. 1 + 2 + 3 + 4 + 5 + 6 = 21.
- With two dice, which total comes up most often? 7. There are six ways to make 7 (1+6, 2+5, 3+4 and back), more than any other total.
- With two dice, what is the lowest total you can roll? 2. One plus one makes two.
- With two dice, what is the highest total? 12. Six plus six makes twelve.
- What is the chance of rolling a 6 on one die? 1 in 6. Six faces, one of them a 6: one chance in six.
- What do people call rolling two ones? Snake eyes. Two single dots look like a snake's eyes.
- How many faces does a d20 have? Twenty. The d in d20 stands for die, and 20 for its faces.
- If you just rolled a 6, is the next roll less likely to be a 6? No, it's the same chance. A die has no memory: every roll is a fresh 1 in 6.
