In this game, the player shoots at goal which is split into 6 regions assigned with the scores, X, as shown in the diagram below. 2 1 4 -3 0 If the shot goes outside of the mini goal player receives a score of O. The following table shows the probability distribution for X 2 4 -1 Score (X) -3 3 12 0 4 12 1 2 12 1 12 P 1 12 Pr(X =) [1] 121 (a) Find the exact value of p. Laura plays the game once. (b) Calculate the expected score. Laura plays the game twice. (e) Find the probability that she has a total score of 5 after two rounds.

R: √(13)

Step-by-step explanation:

Distance formula:

r^2 = (x-h)^2 + (y-k)^2

Center: (h,k)=(-1,5)

Circle: all points of (x,y)=(-3,2)

r^2=(-3+1)^2 + (2-5)^2

r^2=(-2)^2 + (-3)^2

r^2= 4 + 9

r^2=13       ((r^2)^(1/2)) = 13^(1/2) = 3.6055
