Using the below information calculate the conditional probability of C given each of the age groups, or P(C/D), P (C/E), etc. Compare these probabilities and speculate as to which age groups seem more likely than others to have been (according to the legal definition at that time, 0.10% blood alcohol content) intoxicated at the time they were victims.
