Best ResponseYou've already chosen the best response.0hmm.. Is there no gaps between the two circles? and no gaps between the circle and the rectangle? I can't get a fraction, but I can get a decimal probability

Best ResponseYou've already chosen the best response.0This one i'm unsure. I "assume" it's a isosceles right triangle Sin 45º=height/10 => height = 7.07106 Area of triangle = 7.07106*7.07106/2=25 Area of circle = 78.5398 Probability = 25/78.5398=0.3183 The need for assumption isn't good... need a theory for it somehow... but that's all i can do.. sorry
