This is the hardest one thus far!

amistre64 · Answer

you did fine,  what do you suggest we do to finish it?

anonymous · Answer

I started by getting the area of the rectangle = 6*10 = 60
area of the circle = 12.57 
area of the trapezoid = 12
then I got stuck

amistre64 · Answer

well, all your missing then is the concept of probabilty

$$\frac{\#desired.events}{\#total.events}$$
in this case, the desired event is the area of the 2 shapes inside, add them up

and the total even is the area of the rectangle

amistre64 · Answer

24.57
-----
  60

or you might want to hold out a few more decimals before committing

anonymous · Answer

how did you get 
24.57/60?

anonymous · Answer

Oh I got the 12 +12.57 = 24.57

anonymous · Answer

60 is the area of the rectangle - got it
