Answer:

There is a 0.00038147% or 2^18 chance of getting 18 answers correctly by guessing.

Explanation:

Since there is a 1/2 chance for getting one question right, we would divide each quotient by 2 for 18 times. For example, it would go 1/2, 1/4, 1/8, 1/16, 1/32, etc. We would then multiply by 100 to get the percent.

Did the US join the League of Nations following WWI?

uysha [10]

The U.S did not join the League of Nations following WWI. Even the the President of the United States at that time, Woodrow Wilson, was enthusiastic about the organization, they didn't officially join it. The reason why they didn't join it was because of isolationists in congress, in other words, people that didn't agree with what other people are interested in. Because of the war and all of the fatal deaths of Americans, people didn't want the U.S to be affiliated with Europe in any way.
