Question

You spin a spinner that has the numbers 1-20 on it. What is the probability of getting a perfect square?

a.5/20
b.2/20
c.3/20
d.4/20

Answer 1

assuming all the numbers are in spaces of the same size, note that there are 4 perfect squares in the 20 numbers: 1,4 9,16
so, P(square) = 4/20

Answer 2

1/5
