The relative frequency of Event A in an experiment is 13.
Maru [420]

Based on the relative frequency and the number of times the experiment is to be performed, the number of times Event A should occur is 10 times.

<h3>How many times should Event A occur?</h3>

The relative frequency in this regard is 1/3.

The number of times it will occur can be found as:

= Relative frequency x Number of times event was performed

Solving gives:

= 1/ 3 x 30

= 10 times
