Experimental Probability and Theoretical Probability

Experimental Probability is found by repeating an

experiment and observing the outcomes.

number of times an event occurs
P (event)
total number of trials

Example: A coin is tossed 10 times:

A head is recorded 7 times and a tail 3 times.

7
P (head)= P (tail)= 3
10 10

Theoretical Probability is what is expected to happen bassed on

mathematics.

number of favorable outcomes
P (event)
number of trials

Example:
Example 1 :

A coin is tossed.
1
P (head)= 2

P (tail)= 1
2
