Question

A survey of 259 families was made to determine their vacation habits. The two way table below sorts the families by location and the vacations by the length of the vacation.

1-7 days 80 39 37 156
8 or more
days 52 32 19 103
Total 132 71 56 259


What is the probability that a randomly selected family was suburban given that they spent 8 or more days on vacation?
0.12
0.31
0.45
0.50
28.24

Answer 1

We know the family must be suburban so 71/259 will fit that category. We also know they must spend 8 or more days which is 104/259.

Answer 2

*103/259

Answer 3

71/259 is 0.27 and 103/259 is 0.40 .27 times .4 is .11

Answer 4

So your answer is a. 0.12

Answer 5

Another way to figure it out is by taking 32/259 which also gives you 0.12

Answer 6
