A random variable has CDF given by A i=0,1,2 F = 1 i=3 if A = 0.56, then what is p2? A probability density function for the random variable X is given by pi = k()', where k is a constant. What value must k be if X takes on integer values between 1 and n? Hint: n pi = O a. k = r(1-r") if 0 x 1 1-r 1-(3) " O b. k = 3 1-(+)" c. k = 1 1-(1/2)" O 2 d. k = 1-(+)" O e. k = 3 (1)"
