A spinner has three sections. The table shows the results of spinning the arrow on the spinner 80 times Section 1 Section 2 Section 3 18 30 32 What is the experimental probability of the arrow stopping over Section 3?

Directrix (directrix):

From "Web Definitions," The empirical probability, also known as relative frequency, or experimental probability, is the ratio of the number of outcomes in which a specified event occurs to the total number of trials, not in a theoretical sample space but in an actual experiment.

Directrix (directrix):

P(section 3) = number of Section 3 lands divided by the total number of spins. So, P(3rd section) = 32 / ? @hoyo_de_49 What number goes in the denominator of this? Post what you think and we can compare answers, okay?
