<PRE><B>Question 919197</B>
A quiz consists of two multiple-choice questions. The first question has a total of 5 possible answers followed by the second question which has a total of 8 possible answers. If both questions are answered with random guesses
 1)Find the probability that the student gets the first question correct but misses the second question
Ans: (1/5)(7/8) = 7/40
-------------------------------------
 2)Find the probability that the student gets both questions correct:
Ans: (1/5)(1/8) = 1/40
-------------------------------------- 
3)Find the probability that the student answers both questions incorrectly:
Ans: (4/5)(7/8) = 7/10
-----------------------------
 4)Find the probability that the student gets at least one question correct:
Ans: P(at least one correct) = 1 - P(none correct) = 1-(7/10) = 3/10
----------------
