Answer:
Assuming the spinner has 6 equal sectors of different colors, and yellow is only one of those colors, we can say that the probability of the spinner not landing on yellow is 5/6 or approximately 0.8333.
To predict the number of times the spinner will not land on yellow out of 90 spins, we can multiply the probability by the total number of spins:
0.8333 x 90 = 74.997 or approximately 75
Therefore, the best prediction possible for the number of times the spinner will not land on yellow out of 90 spins is 75 times.
