Answer 1

Answer:

P = 1/6 or 0.1667

Step-by-step explanation:

Let A,B and C be the three events and 1,2 and 3 be the three dates. The sample space for this problem is:

{A1,B2,C3} {A1,B3,C2} {A2,B1,C3} {A2,B3,C1} {A3,B1,C2} {A3,B2,C1}

There are six possible outcomes and since there is only one correct answer, the possibility of guessing all 3 questions right is:

P = 1/6

P = 0.1667
