Step-by-step explanation:

Using the rules of logarithms

logx + logy = log(xy)

x = n ⇒ x =

Given

5 + 12 = 7 , then

(5 × 12) = 7 , that is

60 = 7 , thus

= 60 → B

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
