Answer:
64 ways.
Step-by-step explanation:
We are asked to find the number of ways in which a six-question true-false exam be answered.
For each question there are two possible choices that are either true or false.
We have 2 options for all 6 questions.
Total number of ways: [tex]2\cdot 2\cdot 2\cdot 2\cdot 2\cdot 2=2^6=64[/tex]
Therefore, there are 64 ways, in which a six-question true-false exam be answered.
