Answer:
a) 1/16
b) 7/16
Step-by-step 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.
