Question

Transcribed Image Text:A modem transmits a two-dimensional signal (X, Y) given by
X = r cos(27/8) and Y = r sin (27/8),
where is a discrete uniform random variable on the set {0, 1, 2, ..., 7}.
(a) Show the mapping from S to Sxy, the range of the pair (X, Y).
(b) Find the joint pmf of X and Y.
(c) Find the marginal pmf's of X and Y.
=
(d) Compute the probability of the following events: A
C = {X ≥r/√2, Y ≥r/√2} and D = {X <-r/√√2}.
{X = 0}, B = {Y ≤r/√2},
