What is the experimental probability of spinning a 3
?
Solution
The experimental probability of an event is calculated by dividing the number of times the event occurred by the total number of trials.
In this case, the event is spinning a 3, and the total number of trials is 8 (since the spinner was spun 8 times).
Looking at the results, we can see that the number 3 was spun 3 times.
So, the experimental probability of spinning a 3 is 3 (the number of times 3 was spun) divided by 8 (the total number of spins), or 3/8.
