Not me mane. It’s pretty good.
The sum of all numbers is 50. Let's say there have been 50 events, for which property A, B or C holds.
In the center of A, B and C, there is the number 8, which would mean that for 8 out of 50 events, all three properties hold.
The chance of this happening is 8/50 = 4/25 = 0.16
First one is C! Because it explains what’s wrong with the lack of fast food in not populated areas. Second one is B! Because they cannot afford much therefore it’ll have a bad outcome. The last one I was a little confused on but It’s likely A.
-20/27 as:
-8/9 * 5/6
= -40/54
Which simplifies to -20/27
