If there were 100 people in the world how many would speak English?

It's impossible to say for sure how many of 100 people would speak English. Here's why:

* No way to know their origins: We don't know where these 100 people come from. Their native languages would heavily influence how many speak English.

* English isn't universally spoken: While English is a very common language, it's not the primary language for most of the world's population.

To get a more realistic answer, you'd need to consider:

* The geographic location of these 100 people.

* Their individual backgrounds and education levels.
