Answer:
Probability of coin not land on island = 38.25 / 45
Explanation:
Given:
Length of rectangular fountain = 9 ft
Width of rectangular fountain = 5 ft
Side of square island = 1.5 ft
Number of island = 3
Find:
Probability of coin not land on island
Computation:
Area of fountain = 9 x 5
Area of fountain = 45 ft²
Area of three island = 3[Side²]
Area of three island = 3[1.5²]
Area of three island = 6.75 ft²
Probability of coin not land on island = [Area of fountain - Area of three island] / Area of fountain
Probability of coin not land on island = [45 - 6.75] / 45
Probability of coin not land on island = 38.25 / 45
