What is the probability that spinner stops on a perfect square
Solution:
Number on spinner
2, 5, 7, 9 , 12, 16
Total Numbers = 6
Even Numbers = 2 , 12 and 16 = 3
Probability that spinner stops on an even number = 3/6
= 1/2
perfect square = 9 and 16
hence 2 numbers
probability for a player will get a special prize, if spinner stops on a perfect
square = 2/6
