When calculating the experimental probability, we are comparing the number of times the event occurs to the number of times the experiment is done.
P=Times the Event Occurs/Times the Experiment Is DoneThis is very similar to the Probability Formula.
We are told that a total of 8 red, 10 blue, 9 green, and 12 yellow colored tiles were randomly selected. The sum of these values is the number of times the experiment is done.
8+10+9+12= 39 tiles
Out of these, 8 are red, which is the number of times the event occurs. Now we have enough information to calculate P(red).
P=Times the Event Occurs/Times the Experiment Is Done
