Question

A spinner has three sections. The table shows the results of spinning the arrow on the spinner 80 times. What is the experimental probability of the arrow stopping over Section 3? 1/32 3/32 1/3 2/5

Answer 1

The experimental probability is

  (number of times it stopped over Sect. 2) / (total number of times you tried it)

Number of times it stopped in Section-2: 36

Total number of times you tried it:  (20 + 36 + 24)  =  80

Experimental probability of Section-2  =  36/80 = 9/20  =  45%
