Solutions

Expert Solution

There are various possible scenarios possible to get Yahtzee in three rolls. Here is the exhaustive list of the same. The probability of:

  • Four of a kind, then nothing, then matching the last die on the last roll is
  • Three of a kind, then nothing, then matching with the correct pair on the last roll :
  • A matching pair, then nothing, then matching with the correct three of a kind on the third roll :
  • A single die, then nothing matching this, then matching with the correct four of a kind on the third roll
  • Three of a kind, matching an additional die on the next roll, followed by matching the fifth die on the third roll
  • Matching an additional pair on the next roll, followed by matching the fifth die on the third roll is
  • Rolling a pair, matching an additional die on the next roll, followed by matching the last two dice on the third roll
  • Rolling one of a kind, another die to match it on the second roll, and then a three of a kind on the third roll .
  • Rolling one of a kind, a three of a kind to match on the second roll, followed by a match on the third roll is
  • Rolling one of a kind, a pair to match it on the second roll, and then another pair to match on the third roll is

Summing all of the above, we get the required probability as
