A spinner has three sections. The table shows the results of spinning the arrow on the spinner 80 times. What is the experimenta
1 answer:
Experimental probability of the arrow of spinner (rotated 80 times) stopping over Section 1 is one fourth or 0.25.
<h3>What is experimental probability?</h3>Experimental Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event during the experiment.
Given information-
Total number of sections in a spinner is 3.
Total number of times the trials done is 80.
The three section table given in the problem has the values as,
- The values of the first column is section 1 and 20.
- The values of the second column is section 2 and 36.
- The values of the third column is section 3 and 24.
The experimental probability of the arrow stopping over Section 1 has to be find out.
As the experimental probability of an event is the ratio of number of times it took place to the total trails. Thus the experimental probability of the arrow stopping over Section 1 is,
Thus experimental probability of the arrow of spinner (rotated 80 times) stopping over Section 1 is one fourth or 0.25.
