Definition Definition Two-dimentional plane figure composed of a finite number of straight line segments connected to form a closed chain or circuit. A polygonal circuit's segments are known as its edges or sides, and the points where two edges meet are known as its vertices or corners.

Expert Solution

Step 1

Relative frequency can be defined as the number of times an event occurs divided by the total number of events occurring in a given scenario.

Relative frequency= $\frac{s u b g r o u p f r e q u e n c y}{t o t a l f r e q u e n c y}$

Relative frequency= $\frac{f}{n}$
