CHANCE FACTS

1. Chance (probability) says how likely something is, from impossible (0) to certain (1). An even chance is 1/2.
2. When every result is equally likely: chance = favourable results ÷ all results. Rolling a 6 on a die: 1 favourable out of 6, so 1/6.
3. The chance of something not happening is 1 minus the chance that it does.
4. Dice, coins and spinners have no memory. After five reds in a row, the next spin is just as likely to be red as before.
5. A few tries can come out far from the chance. The more tries, the closer the share of results usually gets to the chance.
6. With two dice there are 6 × 6 = 36 equally likely results. Six of them add up to 7, more than any other total, so 7 comes up most.
7. A game is fair when each player has the same chance of winning.
