Question

You have a bull's eye where each section is 2" wide as shown in the diagram. Find the following probabilities.

Answer 1

a) 1/16

b) 7/16

Explanation:

a) The area of the outside circle is π (8")² = 64π in².

The area of the center circle is π (2")² = 4π in².

So the probability is (4π / 64π) = 1/16.

b) The area of the outside strip is π [(8")² − (6")²] = 28π in².

So the probability is (28π / 64π) = 7/16.
