What is the gcf of h4 and h8?
h2
h4
h8
h12

Step-by-step explanation:

GCF mean greatest common factor the both or divisible by h2 and h4 and the greatest of common factor is h4 .

h4

Step-by-step explanation: Both numbers can be divided by 4. 4 is the  greatest number that you can pull out of the equation. So, since you can't pull an 8 out of a 4, h8 cannot be an option. h2 is not an option because there is no h2 in the problem. h12 is not an answer because that would make no sense in this problem.

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
