Question: A random variable X has discrete range Rd = {1, 3}, while its continuous range is the open interval (1, 3), with density in that

A random variable X has discrete range Rd = {1, 3}, while its continuous range is the open interval (1, 3), with density in that interval given by

2(x) = x - 1 1 < x < 3. 3

If it is known that E(X) = 7∕3, calculate the probabilitiesimage text in transcribed
