Answer:
the length of DE is 1/2*9 = 4.5
Answer:
1. P(C AND D) = 0.3
2. (C.) C and D are not mutually exclusive because P(C AND D) ≠ 0
3. (A.) The events are not independent because P(C | D) ≠ P(C)
4.P(D | C) = 0.5
Step-by-step explanation:
• Let P(C) = 0.4
• Let P(D) = 0.5
• Let P(C | D) = 0.6
1.) Find P(C AND D).

2.) Events can be mutually exclusive meaning the both event cannot happen at the same time. So, P(A and B) = 0
3.) Events can be "Independent", meaning each event is not affected by any other events.
4.) Find P(D | C)

Answer:
P = 14.9
Step-by-step explanation:
i used distance formula:
d = √(difference of y-values, squared, + difference of x-values, squared)
distance from (-2,1) and (2,4):
= 5
distance from (-2,1) and (-1,-2): 
distance from (-1,-2) and (2,4):
= 3
P = 5 +
+ 3
≈ 14.9
