Expectation Frequency of An Event In Probability

The expected frequency of an event is the number of events multiplied by the probability of the event itself.

Expectation Frequency of An Event In Probability Formula

For example, in experiment A is done n times, so the expected frequency formula is written as follows:

Fh = n x P(A)

Information :

Fh = Expectation Frequency
n = Number of events
P(A) = Probability occurrence A

Expectation Frequency of An Event In Probability Example

In the experiment of throwing 2 dice together as much as 108 times, please specify the expected frequency of A = {(x, y) | x = 3}, x is the first dice and y is the second dice!

Resolution:
S = {(1, 2), (1, 2),..., (6,6)
n(S) = 36

A = {(3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (3, 6)}
n(A) = 6
