8 0

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.
