A spinner has three sections. This table shows the results of spinning the arrow on the spinner 80 times.
Section 1 Section 2 Section 3
20 36 24
What is the experimental probability of the arrow stopping on Section 1?
Responses
A. 1/4
B. 3/10
C. 1/3
D. 9/20
To calculate the experimental probability of the arrow stopping on Section 1, you need to divide the number of times the arrow stopped on Section 1 by the total number of spins.
Number of times arrow stopped on Section 1 = 20
Total number of spins = 80
Experimental probability = 20/80 = 1/4
Therefore, the correct answer is:
A. 1/4
