Question 86575
write out the sample space, and then write the
indicated events in set notation. 
An unprepared student takes a three-question, true/false quiz in which he guesses the answers to all three questions, so each answer is equally likely to be correct or wrong.
Sample space:
{www,wrr,rwr,rrw,wwr,wrw,rww,rrr}
----------------
a. The student gets three answers wrong.
{www}
----------
b. The student gets exactly two answers correct.
{rrw,rwr,wrr}
-----------------
c. The student gets only the first answer correct.
{rww}
