Question 1099497: Which of the following pairs of probability values could complete the following probability distribution?
x
-3
-2
-1
0
1
2
P(x)
0.13
0.26
p1
p2
0.16
0.19


p1 = 0.09, p2 = 0.40

p1 = –0.1, p2 = 0.36

p1 = 0.26, p2= 0.21

p1= 0.05, p2 = 0.21

The sum of all the probabilities has to be 1.

The sum of the probabilities shown is 0.74; the sum of p1 and p2 has to be 1-0.74 = 0.26.

Only one of the answer choices satisfies that requirement.
