PROBABILITY MATH
posted by HM .
Find the probability of correctly answering the first 4 questions on a multiple choice test if random guesses are made and each question has 5 possible answers.
Explain to me the answer?

The prob of answering a question right (R) is 1/5, and the prob of answering it wrong (W) is 4/5
So you want the specific order of
RRRRW which would be (1/5)^4 (4/5) = 4/3125 
I don't think it requires for it to be times by (4/5)
it is just asking for possibility of it being correct 4 times the first times..
so the answer is 1/625
