Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The probability based on frequency of outcomes during an experiment
A
experimental probability
B
fundamental counting principle
C
mutually exclusive event
D
dependent event
Explanation: 

Detailed explanation-1: -Mathematically, the formula for the experimental probability is defined by; Probability of an Event P(E) = Number of times an event occurs / Total number of trials.

Detailed explanation-2: -Experimental probability is the probability of an event happening based on an experiment or observation. To calculate the experimental probability of an event, we calculate the relative frequency of the event.

Detailed explanation-3: -Relative frequency or experimental probability is calculated from the number of times an event happens, divided by the total number of trials in an actual experiment.

Detailed explanation-4: -Empirical probability uses the number of occurrences of a given outcome within a sample set as a basis for determining the probability of that outcome occurring again. The number of times “event X” happens out of 100 trials will be the probability of event X happening.
