Answer:

1/16

Step-by-step explanation:

Of the 16 ways you can answer the 4 questions, only one of those ways has all answers correct.

Each question can be answered 2 ways, and the answer to each one is independent of the answer to any other. So, there are 2·2·2·2 = 2^4 = 16 ways to answer the 4 questions.
