How many days would it take to finish a 1 pound bag of Skittles?
Assuming average distribution, roughly half of the Skittles will be face down, so you’d be eating half of them each day. Under strictly mathematical analysis, you’d never finish the bag because there’s always half the remainder left. In practice, the number of Skittles is finite and sooner or later there would be only 1 left, and it would come out face down eventually. What you need to do is figure out how many Skittles are in a bag. For example, if Skittles weigh about 1 gram each and there’s 454 grams in a pound, you’d start with 454 Skittles. The consumption would look something like this, assuming 50% chance of any Skittle coming our face up or face down: Day 1 – 454 to start, eat 227, 227 left Day 2 – 227 to start, eat 114, 113 left Day 3 – 113 to start, eat 56, 57 left Day 4 – 57 to start, eat 29, 28 left Day 5 – 28 to start, eat 14, 14 left Day 6 – 14 to start, eat 7, 7 left Day 7 – 7 to start, eat 3, 4 left Day 8 – 4 to start, eat 2, 2 left Day 9 – 2 to start, eat 1, 1 left Day
