3. 2 http://www.mathgoodies.com/lessons/vol6/intro_probability.html A Fair Coin Heads and tails are equally likely. A Fair Die All sides are equally likely. Counters Each counter is equally likely.

4. 3 Coins Different sized coins are not equally likely. A Matchbox Each side is not equally likely. The Weather The weather from day-to-day is not equally likely.

5. 4 In probability all outcomes must be equally likely.

6. 5 P(Event) = Number of favourable outcomes Total number of outcomes P(Red) = 3838 can be a fraction. = 0.375 can be a decimal. = 37.5% can be a percentage.

7. 6 P(Event) = Number of favourable outcomes Total number of outcomes 7878 Numerator Denominator = Rule: Numerator ÷ Denominator 7 ÷ 8 =0.875

8. 7 P(Event) = Number of favourable outcomes Total number of outcomes Rule: multiply by 100 percent. 0.875 =0.875 x 100%= 87.5%
