Best ResponseYou've already chosen the best response.2They give you the diameter is 2, so the radius is 1, and the area of a circle is pi*r^2 = pi* 1 = pi

Best ResponseYou've already chosen the best response.2The probability of hitting the black circle is the ratio of the two areas... \[\frac{ Area~circle }{ Area~white } = \frac{ \pi }{ 100\pi } \approx 0.032\]

Best ResponseYou've already chosen the best response.20 is no chance, and 1 is garunteed 100% , so it is very much closer to zero than 1

Best ResponseYou've already chosen the best response.0So thats the answer for part A

Best ResponseYou've already chosen the best response.2part b is less work, since you know the chance of hitting the circle is 0.032, then the chance of hitting the white area is 1  (chance of circle) = 1  0.032 = much closer to 1 for the white region

Best ResponseYou've already chosen the best response.2Because it is assumed he hits the board somewhere every throw , i guess, no missing
