Persons entering a blood bank are such that 1 in 3 have type ot blood and 1 in 18 have type o blood. Consider three randomly selected donors for the blood bank. Let X denote the number of donors with type ot blood and Y denote the number withtype o blood. Find the probability distributions for X and Y. Also find the probability distribution for Z = X + Y, the number of donors who have type O blood. (Round your answers to four decimal places.)12P(X)P(Y)P(Z)

Here we should find the probability distribution table for X,Y and Z. Please find the step by step…

Answered: Persons entering a blood bank are such…
