Question

30 POINTS! Find the probability that a point chosen randomly inside the rectangle is in each given shape. Round to the nearest tenth

(a) square
(b) not the triangle

Answer 1

P(square) = ((4)(4)/(8)(12)) = 16/96 = 1/6

= 16.7%

P(not the triangle)

= ((8)(12) - (1/2)(4)(5))/((8)(12)) = 86/96

= 43/48 = 89.6%
