1. Recapping: Theoretical probability
Which numbers could be on the spinner for the probabilities to be true?
ANS
P(Odd Number) = 2 5

2. Probability Experiment
Learning Objective: Compare theoretical and experimental probabilities.
Decide on six integers that can be placed on the spinner to give the following probabilities.
P(Even) = 1 2
P(Prime) = 1 3
P(Neither even nor odd) = 1 6
P(Factor of 36) = 1 3
P(Multiple of 10) = 1 6
P(Less than 30) = 1

4. Probability Experiment
Learning Objective: Compare theoretical and experimental probabilities.
Conclusions
1. Is this spinner biased towards a particular event? Was this expected?
2. If there is any unexpected bias, what may have caused it?
3. Is there a way to reduce bias in the future?
