The experimental probability of the arrow stopping on Section 2 will be
. is the ratio of the favorable event to the total number of events.
<h3>What is probability?</h3>
Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1.
No of arrows given in the different section ;
Section 1=18
Section 2=30
Section 3=32
The probability that the arrow stopping on Section 2 is found as;

Hence, the experimental probability of the arrow stopping on Section 2 will be
.
