Suppose that 3 out of 19 doctors in a small hospital are trained in special procedures, 12 of the doctors are over the age of 40 and 2 is both trained in special procedures and over 40. What is the probability that you are randomly assigned a doctor that is either trained in special procedures or over the age of 40?
