Let be a Rayleigh random variable whose PDF is fa (r) = crexp (0-r2) u (r). (a) Find the value of the constant c. (b) Find Pr (R >r) for an arbitrary constant r. (c) Find Pr (R > 1 | R < 2). A digital communication system sends two messages, M = 0 or M = 1, with equal probability. A receiver observes a voltage which can be modeled as a Gaussian random variable, X, whose PDFs conditioned on the transmitted ...Mr. Hood is a good archer. He can regularly hit a target having a 3- ft. diameter and often hits the bull’s- eye, which is 0.5 ft. in diameter, from 50 ft. away. Suppose the miss is measured as the radial distance from the ...A random variable has a CDF given by (a) Find Pr (X =0) and Pr (X=1). (b) Find Pr(X 1/2). (c) Find Pr(X > 1/2|X >0). Suppose X is an integer- valued random variable. Show that in this case, ϕX( 2πn) = 1 for any integer, n . Likewise, prove the reverse is also true. That is, show that if ϕX( 2πn) = 1 for any integer, n , the random ...Post your question
