Square A has an area of 65 square centimeters. Square B has a perimeter of 16 centimeters. If square B is placed within square A and a random point is chosen within square A, what is the probability the point is not within square B? Choices:
A) 0.25
B) 0.5
C) 0.75
D) 0.1
E) 0.3
I guess it's mean that square B is placed within square Aentirely.   Since, the perimeter of B is 16, then its side is 16/4=

4 and the area is 4^2=16;   Empty space between the squares is 65-16=48 square centimeters, so if a random point is in this area then it won't be within square B: P=favorable/total=48/64 = 0.75.   Answer: 0.75
