Two types of permutation Permutation with repetition A combination lock. It can be 222 Permutation without repetition You're competing at a track and field race. You can only be first,second or third. You can't occupy first and second at the same time
i.e. List all permutations of the letters in the word CAT.
that's just a three letter word.
wait... three letters... that's 3 x 3 x 3 = 27 if we allow those letters to be repetitive though.
but there's no CCAT or anything like that .. that would be 4!/2!
so without repetition, we have: \(3 \times 2 \times 1 \) since we have 3 letters, which corresponds to 3 events. Meaning in our first event, it does not matter if we picked C, A or T. Then for our second event, we have only 2 letters left, because we exclude the first event that occurred; then it follows that we have one event left for the third event.
without repetition: \(\large _nP_n \): number of permutations of "n" things taken "n" at a time. \(\large _nP_n = n! \)
20 people are running for an office in an election. In how many ways can you choose a President (P), Vice President (VP), and Secretary (S).
\(\sf P:20; VP: 19; S:18\) \(20 \times 19 \times 18 = 6840\) Permutations of "n" elements taken "r" at a time. \(\large _nP_r = \frac{n!}{(n-r)!} = \frac{20!}{(20-3)!} = 6840 \)
