Question

A spinner is spun 77 times and stops on the color green 17 times. Calculate the experimental probability of the spinner stopping on the color green.

Answer 1

`\boxed {\boxed {\sf \ \frac {17}{77}}}}`

Explanation:

The experimental probability is the probability of an event occurring in an experiment that was conducted. It is the ratio of the times an event occurred to the total trials.

`P(event)= \frac{ number \ of times \ event \ occurs} {total \ number \ of \ trials}`

We are trying to find the experimental probability of landing on green.

• The spinner was spun 77 times. This is the total number of trials.
• The spinner landed on green 17 times. This is the event.

`P(green)= (17)/(77)`

This fraction cannot be simplified any further, so the experimental probability of landing on the color green is 17/77
