Tate · Answer 1

The probability of correctly guessing the answer to each one of the four questions is 1/3.

Therefore the correct choice of answer is C.

Scruffy · Answer 2

The fourth question is an independent event and that Leanna can choose from 3 choices. Only 1 of the 3 choices is right. Therefore, the probability of getting the correct answer is 1/3. The answer is letter C. 1/3.
