A spinner has three sections. This table shows the results of spinning the arrow on the spinner 80 times.
UNO [17]

The experimental probability of the arrow stopping on Section 2 will be \rm \frac{3}{8}. 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;

\rm P = \frac{Favourable \ outcomes }{Total \ outcomes }  \\\\\ P= \frac{30}{18+30+32} \\\\ P=\frac{30}{80}\\\\ P= \frac{3}{8}

Hence, the experimental probability of the arrow stopping on Section 2 will be \rm \frac{3}{8}.

More about the probability link is given below.
