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 = $\frac{Number \ of \ successful \ trials}{Total \ number \ of \ trials}$

The relative frequency calculator finds the relative frequency when you plug in the number of individual frequency with total number of frequency.

**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.

**Step 1 :**Jot down the given values from the problem.

**Step 2 :**Determine the relative frequency by substituting the values into the formula.

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.

**Solution:**

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".

**Solution:**

Given : frequency of getting "head" = 30

total outcome = 75

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