To make the best prediction for the number of times the spinner will land on yellow or pink after 72 spins, we first need to determine the probabilities of landing on yellow and pink.
Assuming the spinner is evenly divided among its sections and you’ve identified the fractions for yellow and pink, you can add those probabilities together.
For example, if yellow is 1/4 of the spinner and pink is 1/4, then the combined probability of landing on yellow or pink is:
1/4 + 1/4 = 1/2.
Now, multiply this probability by the total spins:
1/2 * 72 = 36.
So, the best prediction for the number of times it will land on yellow or pink is 36.
