please explain your work

Answer 1

the cup will land on its side 310 times and it'll land on the end 55 times

Explanation:

To determine the amount of times it lands on the side, take the days in a year, 365, and multiply that by .85, which gets you 310. To get the amount of times it lands on its end, just subtract 310 from 365.
