Answer:
2. 150 permutations
3. 19,958,400 permutations
4. 20,160 permutations
5. 34,650 permutations
Step-by-step explanation:
Formula.
PR = n!/p!q!
where: n is the number of letters in a word
p, q are the repeated letters
2. PR = 5!
PR = 120
(since walang repeated letters, wala ring denominator)
3. PR = 11! / 2!
PR = 39,916,800 / 2
PR = 19,958,400
(may dalawang T, kaya may 2! as denominator)
4. PR = 8! / 2! 2! 2!
PR = 40,320 / (2×2×2)
PR = 40,320 / 8
PR = 20,160
(may tatlong 2! sa denominator dahil merong repeated letters, - 2 C, 2 L, 2 U )
5. PR = 11! / 4! 4! 2!
PR = 39,916800 / (24×24×2)
PR = 39,916,800 / 1,152
PR = 34,650
(may 11 letters sa word na MISSISSIPPI, at may 4 I, 4 S, at 2 P)
