I need help estimating how many jellybeans there are in the world. Can we work through a Fermi calculation of this together?

Absolutely. You’ve set a tough problem, but I’m happy to do my best.

Great. So I'd estimate that people consume an average of 2 jellybeans a year, since most people consume none but jellybean enthusiasts might consume many. That means there are around 15 billion jellybeans eaten per year. Jellybeans last about a year so I'm going to guess that there are 15 billion jellybeans in the world at a given time. Does that seem right to you?
