Question
the area of a yard is 420 ft. what is the probability that any leaf landing in the yard will land ina circular wading pool that has a diameter of 14 ft?
Answers
Reiny
area of circle = π(7^2) = 49π
prob of landing in circle = 49π/420 = 7π/60 = appr .3665
ignoring any leaves that fall partially either on the circle or the edge of the yard
