To find the relative frequency of people who prefer hiking also prefer mountains, we need to divide the number of people who prefer hiking and mountains by the total number of people who prefer hiking.
Number of people who prefer hiking and mountains = 45
Total number of people who prefer hiking = 45 + 20 + 12 = 77
Relative frequency = (45 / 77) x 100 = 58.4%
Therefore, the relative frequency is 58.4%.

To find the relative frequency of people who prefer island vacations also prefer swimming, we need to divide the number of people who prefer island vacations and swimming by the total number of people who prefer island vacations.
Number of people who prefer island vacations and swimming = 40
Total number of people who prefer island vacations = 12 + 40 = 52
Relative frequency = (40 / 52) x 100 = 76.9%
Therefore, the relative frequency is 76.9%.

To find the relative frequency of people aged 12-15 who had over 500 messages, we need to divide the number of people in that category by the total number of people in that age group.
Number of people aged 12-15 who had over 500 messages = 78
Total number of people aged 12-15 = 24 + 47 + 78 = 149
Relative frequency = (78 / 149) x 100 = 52.3%
Therefore, the relative frequency is 52.3%.

To find the percentage chance that a person prefers cherries and is from the North, we need to divide the number of people who prefer cherries and are from the North by the total number of people who prefer cherries.
Number of people who prefer cherries and are from the North = 120
Total number of people who prefer cherries = 120 + 25 = 145
Percentage chance = (120 / 145) x 100 = 82.8%
Therefore, the percentage chance that a person prefers cherries and is from the North is 82.8%.
