WebbThe number of ways this may be done is 6 × 5 × 4 = 120. Using factorials, we get the same result. 6! 3! = 6 · 5 · 4 · 3! 3! = 6 · 5 · 4 = 120.

Webb3 dec. 2024 · It would be a good shortcut to just write 5-1-1-1 and note that there are 4 different positions to put the 5, so we count 4 partitions of this type. Similarly, 4-2-1-1 has 12 orderings, C (4,2), since there are 4 possibilities for which child gets the 4 times 3 possibilities for which other child gets the 2. WebbIf you can calculate a probability using logic and counting you do not NEED a probability rule (although the correct rule can always be applied) Probability Rule One Our first rule simply reminds us of the basic property of probability that we’ve already learned.
