Find the probability that -2 Enter

Explanation:

Use a marker to highlight the columns that span from x = -2 to x = 2, including both endpoints. The P(x) values that are highlighted are then added up

0.33+0.16+0.11 = 0.6

There's a 60% chance we randomly select an x value such that

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0

i think it is 18
