Experimental Probability

Socrative Starter


1) To be able to calculate the relative frequency of an event happening.

2) To be able to calculate the expected outcome of an experiment repeated multiple times.

3) To be able to design an experiment to test a hypothesis.

What is the probability of rolling a 4 when we roll a dice? How can we calculate the experimental probability? What parts of the experiment do we need to take into account?

Was the relative frequency what you expected it to be? If not, what could be the reason?

Experiment 2, Counter Drop

How can we calculate the probability of when you drop a counter it lands curved side up?


What was the result of the experiment? Was it what you expected? If you repeated the experiment 1000 times, how many curved side downs would you expect?
