1. Look at this spinner.<br />
Some sectors are striped, some are spotted,<br />
and some are solid colours. The pointer is spun.<br />
Use a fraction, a decimal, and a percent to describe the probability<br />
of each event.<br />
a) The pointer will land on a blue spotted sector.<br />
b) The pointer will land on a striped sector.<br />
c) The pointer will land on a solid yellow sector.<br />
d) The pointer will land on a red sector.<br />
2. Jenna and Vijay place 50 coloured tiles in a bag.<br />
They use 25 green tiles, 10 red tiles, 5 yellow tiles, and 10 blue tiles.<br />
One tile is picked without looking.<br />
Jenna says,<br />
Vijay says,<br />
The probability<br />
of picking a<br />
green tile is 1 2 .<br />
I think<br />
the chance of<br />
picking red<br />
is 50%.<br />
Who is right? Explain your thinking.<br />
3. Draw a spinner.<br />
Colour it so that the probability of spinning blue<br />
is 40%, red is 30%, green is 20%, and yellow is 10%.<br />
Describe how you divided the spinner into sectors<br />
and decided how to colour the sectors.<br />
