Answer:

On the right is a circle with centre (0, 0), radius r and (x, y) any point on the circle. Distance between (0,0) and (x, y) equals the radius, r. If the centre is (0, 0), the equation of the circle will be of the form x2 + y2 = r2.

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 $\rm \frac{3}{8}$ .
