AN INTEGER IS RANDOMLY SELECTED AND PERMANENTLY REMOVED FROM THE SET OF 100 INTEGERS (1,2,3,...100). WHAT IS THE MINIMUM NUMBER OF TIMES THIS REMOVAL PROCEDURE WILL HAVE TO BE DONE TO GUARANTEE THAT AN INTEGER HAS BEEN REMOVED?
SRRY I MEANT AN EVEN INTEGER HAS BEEN REMOVED LOL
You may have to clarify, do you mean how many times will this have to be done to guarantee the removal of an even or odd integer? Because just removing one integer guarantees the removal of an integer.
In either case though, you have to think. How many even or odd numbers are there between 1-100? The answer is 50. So in order to guarantee the removal of an even number 51 integers must be randomly removed.
I MEAN AN EVEN SORRY!
