Answer:


(1)/(1892)

Explanation:

There are two possibilities for each of 13 questions, true or false. As a result, you have a
(1)/(2) chance of choosing either of the choices. To find this, you would multiply the probability to the power of the number of cases, meaning
((1)/(2^(13)))=(1)/(1892).
