Question

Find the probability that a chosen point at random in the trapezoid shown lies in either of the shaded regions.

Answer 1

now this i do remember, 4 and 5 i got mixed up in lol

Answer 2

probability = area of shaded parts / area of tapezoid

Answer 3

how do i find the area

Answer 4

oh yes amist - lol!

Answer 5

Area of trapezoid = [h(a+b)]/2 where h is the height, and 'a' and 'b' are the parallel sides.

Answer 6

then how do i find area of shaded parts

Answer 7

Find the area of the square


Area of shaded parts = Area of trapezoid - Area of square

Answer 8

i got 3.5 is it right?
