PLZ HELP WILL GIVE BRAINLIEST!!!!! AND 20 POINTS!!!!!!!!!!!!!!

A board game uses a number spinner that is divided into four equal sections. A game tester spins the dial 20 times, 100 times, and then 500 times. She records the results in a frequency table.

Number of trials
Outcomes 20 100 500
1. 4 19 120
2. 6 32 127
3. 7 28 132
4. 3 21 121
based on the test using 500 spins, what is the experimental probability of spinning a 4?

In the 500 spin test, 4 was chosen 121 times.  This mean it was chosen 121 times out of 500, or 121/500.

Now, we need to convert this into a percent.  We do this by dividing the numerator by the denominator, and multiplying the result by 100.

121/500 * 100 = 24.2, so the probability of spinning a 4 is 24.2%.

That would be 121/500 of a chance, or roughly 24%.

I hope this helped! If you have any further questions or concerns, feel free to ask me! :)
