# Real world example of binomial expansion? watch

1. Howdy . I can't find a decent example of why the Binomial expansion is used in the real world with the maths to follow it.

Could someone explain how it is used in the real world and give me an example of the actual maths please?

I only seem to come across websites saying what it is used for, but not actually giving an example using the maths behind the expansion.

Thanks
2. It's used quite a lot in computing, economic forecasts and probabilities, mechanics… although I don't see myself needing it anytime soon

Im pretty sure binomial expansion finds probability of something. So it can be used in economics to show profit or in weather.

SO if i said theres a .30 chance of snow and a .7 chance of rain
using this info and binomial expansion you could find the probability of it snowing 30 days in a row
