"false", of
wich he is only sure of the answers he
gave
five questions, he answers the remaining
five at randone
What is the probability of that accredits at

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
