Statistics and Probability — Chance<br />
Rock, paper, scissors<br />
Rules: Children on the count of three make a<br />
hand signal for rock, paper or scissors. Rock beats<br />
scissors; scissors beats paper; and paper<br />
beats rock.<br />
Draw straws<br />
Rules: One child holds enough straws for all<br />
players to have one each, hiding their length.<br />
One straw must be cut shorter than all the others.<br />
Players draw one straw randomly. <strong>The</strong> player with<br />
the shortest straw loses.<br />
Roll a dice<br />
Rules: All players roll<br />
a dice. <strong>The</strong> player<br />
with the highest<br />
number wins.<br />
Rock, paper, scissors<br />
Coin flipping<br />
Rules: One child flips a coin and the other child<br />
guesses if it will land heads up or tails up.<br />
Think of a number<br />
Rules: One child thinks of a mystery number<br />
between two given numbers. Players guess a<br />
number in that range. <strong>The</strong> player with the closest<br />
number to the mystery number wins.<br />

(a) 100%<br />
(b) 20%<br />

probability of selecting the correct<br />
number is:<br />
(a) 0.8 (b) 0.10 (c) 0.125<br />
15 True or False?<br />
<strong>The</strong> greater the range of numbers,<br />
the greater the chance of selecting the<br />
correct mystery number.<br />
16 Select the statement which justifies<br />
which game has more chance of<br />
winning—Coin flipping or Roll a dice.<br />
(a) Coin flipping has more chance of<br />
winning because it only has two<br />
choices available.<br />
(b) Roll a dice has more chance of<br />
winning because it has more<br />
numbers to choose from.<br />
