Answer by ilana(307)   (Show Source):
You can put this solution on YOUR website! For each question, you need to know the total successful cases and the total possible cases (give the necessary conditions).
a) There are no necessary conditions, so the total possible is the total travelers, 254. The total successful is the amount of males, 118. You should be able to divide to find the probability on your own. (You can write this as a fraction or a percent.)
b) The necessary condition (given) is that the traveler is female. So the total possible is the total number of females, 136. Now, looking at only the females column, the successful amount is the number on vacation, 64. Again, divide to find the probability.
c) The necessary condition (given) is that the traveler is on vacation. So the total possible is the total number on vacation, 135. Now, looking at only the vacation row, the successful amount is the number of males, 71. Once again, divide to find the probability.
