Question

A student ran out of time on a multiple choice exam and randomly guessed the answers for 2 problems. Each problem had 5 answer choices -a,b,c,d,e and only one correct answer. What is the probability that she answered both of the problems correctly

Answer 1

so if there are 5 choices and only one is correct, there is a 1/5 chance of being correct. since there was 2 questions, you need to multiply 1/5 by 1/5 to get 2/25 of getting both questions correct.

i hope this helps!!
