   Question

   Suppose you drill a hole and then measure it. We define the event A if the diameter of the hole is larger than 2.3 cm and smaller than 2.5 cm. What then is the complement event of A, if $\bar{A}$?

   
   
   1. FALSE: $\bar{A}$ = {the diameter of the hole is less than 2.3 cm}
   2. FALSE: $\bar{A}$ = {the diameter of the hole is greater than 2.5 cm}
   3. FALSE: $\bar{A}$ = {the diameter of the hole is greater than 4.8 cm}
   4. TRUE: $\bar{A}$ = {the diameter of the hole is less than 2.3 cm or greater than 2.5 cm}
   
   
   1. $\bar{A}$ = {the diameter of the hole is less than 2.3 cm}: Incorrect
   2. $\bar{A}$ = {the diameter of the hole is greater than 2.5 cm}: Incorrect
   3. $\bar{A}$ = {the diameter of the hole is greater than 4.8 cm}: Incorrect
   4. $\bar{A}$ = {the diameter of the hole is less than 2.3 cm or greater than 2.5 cm}: Correct
