If you spin the spinner 12 times, what is the best prediction possible for the number of times it will land on yellow?

The best prediction possible for the number of times it will land on yellow is 2 times. This prediction is based on the assumption that the spinner is fair and all outcomes have an equal chance of occurring. Since there are 5 different colors on the spinner (including yellow), and 12 spins in total, the expected frequency of the spinner landing on yellow would be 2 out of 12 spins.
