Stephen conducts an experiment with a spinner divided into 4 equal sections, as
shown in the diagram below. He spins the spinner 20 times and records his results in the table
below.
What is the experimental probability of spinning a 3?


2.

Refer to the results from Stephen’s experiment in question 1. What is the
experimental probability of spinning a 4?
a.  2  b.   c.  10  d.  


3.

Refer to Stephen’s experiment in question 1. What number is Stephen most
likely to get on the 21st spin?
a.  1  b.  2  c.  3 or 4  d.  all numbers are equally likely

7.

Carly places a blue, a red, and a yellow cube in a bag. She removes a cube from
the bag, records the colour, and then puts the cube back into the bag. Carly does this 25 times. The
results of her experiment are shown in the table
below.
What is the experimental probability of choosing a blue cube?


8.

Refer to Carly’s experiment in question 7. What is the experimental
probability of choosing a red cube?


9.

Refer to Carly’s experiment in question 7. If you were to remove a cube
from the bag a 26th time, which colour would you be most likely to get?
a.  red  b.  blue  c.  yellow  d.  all colours are equally likely 


10.

Refer to Carly’s experiment in question 7. If a green cube were added to
the bag, what is the probability of picking the green cube?
a.   b.   c.  4  d.  1
