I can't even complete the graph on this one ^
Here's just the first one:
80 members would buy one, the other, or both. That means 125 - 80 , or 45 members would not buy either type.
The rest of the numbers I found by subtracting the total from the other numbers in the row or column.
So the probability that a randomly selected gym member would buy passion fruit but not tropical grape is...
19 / 125 = 15.2% ≈ 15%
