I would say that Betty will have a probability to guess 1/3 on the fourth question due to the test only having 10 multiple choice questions with three answers.

Answer: $\dfrac{1}{3}$

Step-by-step explanation:

Given: The number of multiple choices to each question = 3

We know that in multiple choice question there is only one answer is correct .

Then the probability that she will guess correctly on any question is given by :-

$=\dfrac{\text{Correct choice}}{\text{Total choices}}\\\\=\dfrac{1}{3}$

Hence, the the probability that she will guess correctly on the fourth question = $\dfrac{1}{3}$
