I need to figure out the odds, or probability, of something happening.
Say there are 254 ping pong balls are mixed in a bag where 68 of them are red and the other 186 are white. So, 27% of the balls are red. Someone who is blindfolded reaches into the bag twelve times and selects one ping pong ball each time. What are the odds that all 12 ping-pong balls will be white?
can anyone point me to an odds/probability calculator that will help me establish the percentages on this? Or is anyone adept at this type of calculation that can answer this question?
thanks
