​Lesson 7.3

Understand Experimental Probability​

Some text here about the topic of discussion

Definition:

Experimental Probability: The ratio of number of times an event actual occurs to the number of times the event was carried out. (Also known as the relative frequency.)

Ex: If you flip a coin 50 times and it lands on heads 30 times your experimental probability of a coin landing on heads would be 30 out of 50.​

Key Concept:

Experimental Probability = Number of times an event occurs

Total Number of Trials​

​

Ex: You roll a dice 20 times and it lands on 5 twice. What is the experimental probability of rolling a 5?​
