Suppose you have a bag filled with 6 blocks numbered from 1–6. You consecutively choose three blocks, without replacement to form a three-digit number. You choose the first number and put it in either the hundreds, tens, or ones place. You choose the next number and put it in one of the remaining places, and so on. The object of the game is to create the greatest three-digit number. What is the probability of getting a higher number in the third draw (than the second draw) if a 5 is in the tens place and the second draw is a 2? |
