Coin Landing on its side

[CanadaAotS]

Alright, so the site said that you have to assume that theres a sphere surrounding the coin that has its center point at the center of gravity. The rims of the coin are supposed to be touching the surface of the sphere.

 

To figure out the probability of the coin landing on its edge you'd have to find the surface area of the "equator" so to speak. The area where the rim is.

 

The site said you'd need calculus... how exactly would you do this? I'm in calculus now but I can't think of how lol

The probability would probably be lower than that, because if it is on its side it would stay there, while the edge is very unstable... Very low probability of it happening, but it happens

 

ps: did you make that avatar lyssia? I like it
