1. A Russian gangster kidnaps you. He puts two bullets in consecutive order in an empty six-round revolver, spins it, points it at your head and shoots. *click* You’re still alive. He then asks you, “do you want me to spin it again and fire or pull the trigger again right away?” For each option, what is the probability that you’ll be shot?

SPOILER ALERT! 

There are 4 ways to arrange the revolver with consecutive bullets so that the first shot is blank. These are the possible scenarios:

  1. (xBBxxx)
  2. (xxBBxx)
  3. (xxxBBx)
  4. (xxxxBB)

The other two scenarios would have meant you got shot on the first attempt. (BBxxxx) or (BxxxxB)

Now, look at the second slot in those 4 possible scenarios above. Your odds of getting shot are 1/4 or 25%. (Only #1 would get you shot)

But if you respin… there are 2 bullets remaining and 6 total slots. 2/6 or 33%.

2. Why are manhole covers round?
