Step-by-step explanation:

as we can see on the given point :

9 quarts of red paint are mixed with 13.5 quarts of yellow paint.

13.5/9 = 27/18 = 9/6 = 3/2

so, the last answer (3:2) is correct.

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
