Ask a cleverly worded question

"Right hmmm what outfit are you wearing?" She asked the nurse.

The nurse giggled then answered.

" I am wearing a cops uniform silly."

Well that was easy . Alex thought.

"Okay Bunny girl how do I get out of this room?"

The bunny girl smiled.

"I do not know the nurse knows the code that you need to type into the screen there"

Ah great this was going to be a lot harder than Alex had first thought.

"How many questions do I have, Is there a time limit?" Alex asked the bunny.

"You have 15 questions at the start and your time limit is not know to me the nurse knows."

Of course she does...15 at the start and she had use 3 so far.

Alex looked down at the screen thankfully it was only a 3 digit code to guess.

" Right Nurse are the numbers 123 in the code at all?

"Yes!"

Okay well that narrows it down to the number 4,5,6,7,8,9,0 in any possibly order.

Alex had to do this smartly she did not have unlimited time or questions. She needed to think of something.
