Answer:

idk

Step-by-step explanation:

if not i would help sorry

Answer:

1 answer. (possibly 2)

Step-by-step explanation:

There's [tex]\frac{1}{4}[/tex] chance they get the correct answer for a question.

That means if they answer 4 questions, they can expect 1 answer to be correct. If they answer 6 questions, they can expect 1.5 answers to be correct but you can't have 0.5 of an answer so they can expect 1 question answered correctly.
