Students from 4º ESO A-B performed an experiment about probability when the odds of the elementary events are unpredictable such as when a drawing pin is thrown
This was the activity they did
Throw the drawing pins on the
table, and count how many drawing pins are up and how many are down .

- Assign probabilities to the up
and the down drawing pin.
We think that the probability of having the drawing pin up
should be ____ and down should be ______. For these numbers we have used
___________________
- Can you use Laplace’s rule?
Why?
We can/can’t use Laplace rule because we think that to have the drawing pin up or down is/ isn’t equally likel
And you can see below their results
The conclussion is that the probability of having an up drawing pin is 2/3 and down drawing pin is 1/3
