NAME: QUESTION 3 3. Your DC ground voltage V drifts randomly from 0. V's magnitude can be described by a random variable X = |VI. V's sign can be described by the event A = {V 2 0}. (Given A, V = X. Given A, V = -X.) Say we know: P(A) = ;, X ~ Exponential(1), and X II A, i.e. fxIA(x) = fXIA(x) = fx(x). (a) (2 pts) Find P (V s v| A) and P (V s v|A"). Hint: rewrite V in terms of X and separate v 2 0 and v
