Question

A spinner has three sections. The table shows the results of spinning the arrow on the spinner 80 times.

What is the experimental probability of the arrow stopping over Section 1?
Section 1 Section 2 Section 3
28 36 16

Answer 1

Answer:
`(7)/(20)`

Explanation:

From the given table, The number of times arrow comes results in section 1= 28

The total number of times spinner spins =80

Now, the experimental probability of the arrow stopping over Section 1 is given by:-

`\text{P(Section 1)}=(28)/(80)=(7)/(20)`

Hence, the experimental probability of the arrow stopping over Section 1 is
`(7)/(20)`
