Use the counting principle to determine the number of elements in the sample space. The possible ways to complete a true-false examination consisting of 26 questions.

2^26

Step-by-step explanation:

For a true - false examination ; number of options or possible outcomes = 2

Number of questions = 26

Using the counting principle ; the number of elements in the sample space ;

(2 * 2 * 2 *... * 2) for the entire 26 questions

This is equivalent to : 2^26

2^26 = 67108864
