Relative Frequency Calculator

Frequency estimates how many times an event occured. The relative frequency is the number of successful outcome divided by the total number of outcomes.

Relative frequency formula :

Relative frequency = $\frac{Number \ of \ successful \ trials}{Total \ number \ of \ trials}$
The relative frequency calculator finds the relative frequency when you plug in the number of individual frequency with total number of frequency.

Some problems are solved based on relative frequency below.

Solved Examples

Question 1: A dice was rolled 160 times and "5" occurred 20 times . Determine the probability of getting "5" on dice.
Given : frequency of getting "5" = 20
total outcome = 160

Relative frequency of getting "5" = $\frac{20}{160}$ = $\frac{1}{8}$

Question 2: Sigma tossed a coin 75 times and "Head" was shown 30 times. Determine the probability of getting "head".
Given : frequency of getting "head" = 30
total outcome = 75

Relative frequency of getting "head" = $\frac{30}{75}$ = $\frac{2}{5}$
