Math's time!

22/07                                                   WALT: Probability

What is the chance that I pull out a blue counter?

4/8 = 2/4 = ½ = .5 = 50%

What is the chance that I pull out a pink counter?

2/8 = ¼ = .25 = 25%

What is the chance that I pull out a green counter?

1/8 = .125 = 12.5%

What is the chance that I pull out a yellow counter?

1/8 = .125 = 12.5%

Outcomes:

Blue

Pink

Blue

Yellow

Green

Tomorrow we will be looking at the probability of more than one outcome. What is the chance of pulling out a blue and a pink? How do you think you would work that out?
