A. If a person is selected at random, what is the probability it is his/her 2nd cruise? (total of 2nd cruise column)/(grand total)
B. If a person is selected at random, what is the probability the person is either in the age group 31-40 or 41-50? (sum of those rows)/grand total)
C. If a person is selected at random, what is the probability the person is either 21-30 or on his/her 2nd cruise? (sum of 21-30 and 2nd - intersection
of that row and column)/grand total
D. If two people are selected at random, what is the probability they are both on their 1st cruise? 144C2/grandtotalC2
