you have 4 fields where it can land, so the probability has a denominator 4.
2 of those fields have a even number so the numerator is 2.
-> probability is 2/4= 1/2
So each foot is 12 inches so to remove 8 feet to get 12 in you need to remove 8 times 12 inches total or 96 in and each cut removes 1/8 in so times 96 by 8 and get 768 total cuts
