Question 1061877
Grade X-Amity will be given a test consisting of ten true-ir-false questions. If a penalty is imposed for each incorrect answer, so that a student may leave some questioned unanswered, in how many ways may the exam be completed? 
-----
Each question may be answered in three ways:: correct, incorrect, unanswered
-----
Ans: # of way completed for the 10 is 3^10 ways = 59049 ways
