hmm I would have guessed 1/5, but it must have something to do with starting on 50
swissgirl
  • swissgirl
But it can be 50 since the number is greater than 49
zzr0ck3r
  • zzr0ck3r

imagine a 1:4 ratio of some liquid and water for every 4 gallons of water you put in one gallon of some liquid if you do this once, you have put in 1/5 of the whole
swissgirl

  • anonymous
weird way to put the answer
HELP!!!!
  • HELP!!!!
I SI
swissgirl
  • swissgirl
Ok so basically the probability that you will get a multiple of 5 is a 1/5 meaning that for every 5 picks one out of the 5 picks will be a multiple of 5. In other words 1 pick will be a multiple of 5 while the other 4 will not. Do you follow @HELP!!!!
