Seven of eight earns the star. Stars are saved on this device, and to your account when you are signed in.
Remember
- Certain: it will happen. Impossible: it cannot happen. Likely is more than half the chances; unlikely is fewer than half.
- The colour with the most sections or marbles is the most likely.
- Chance as a fraction: the ones you want over all of them. 3 red out of 8 is 3/8. Then simplify.
- Expected number = chance × number of spins. Real results come close, but are rarely exact.
- Two coins have 4 outcomes (HH, HT, TH, TT); a coin and a dice have 2 × 6 = 12.
- On the chance line, 0 is impossible, ½ is an even chance and 1 is certain.
