Only 70% of the pints of human blood donated at blood banks are suitable for hospital use. The remaining 30% are not suitable due to various infections in the blood. Suppose we randomly choose 18 donated pints of blood from a blood bank. Assume these pints come from randomly selected citizens. Our selections of blood pints are independent from one another. Let X be the number of selected pints of blood which are suitable for hospital use. Let Y be the number of selected pints of blood which are not suitable for hospital use. Let p = the probability of a particular randomly selected pint of blood being suitable for hospital use a. What is the value of p as a decimal? b. What is the probability that X = 12?| c. What is the probability that X > 12?
