Answer: 0.76
Step-by-step explanation:
Given : Number of sections ( yellow, brown, red and orange) = 4
The spinner is spun 50 times and lands on brown 12 times, then the number of times spinner does not land on brown = 50-12=38
Then, the experimental probability that the spinner does not land on brown :_

Hence, the experimental probability that the spinner does not land on brown = 0.76
