What is relative frequency?

Back

Relative frequency is the ratio of the number of times an event occurs to the total number of trials or observations. It is often expressed as a decimal or percentage.

Front

How do you calculate relative frequency?

Back

Relative frequency is calculated by dividing the number of favorable outcomes by the total number of outcomes. Formula: Relative Frequency = (Number of Favorable Outcomes) / (Total Outcomes).

Back

The area of a triangle is given by the formula: Area = (1/2) * base * height.

Front

What is the relationship between the sides of a right triangle?
