As the vowel, A and E will remain at their respective position ⇒ Total number of arrangements = 3! But due to the repetition of P, we get ⇒ Total number of arrangements will be = 3!/2! = 6/2 = 3 ∴ The number of arrangements of the word ‘APPLE’ where vowels will not change their positions is 3

The 5 letters word APPLE can be arranged in 60 distinct ways. The below detailed information shows how to find how many ways are there to order the letters APPLE and how it is being calculated in the real world problems.
Distinguishable Ways to Arrange the Word APPLE
Objective: Find how many distinguishable ways are there to order the letters in the word APPLE. Step by step workout: step 1 Address the formula, input parameters and values to find how many ways are there to order the letters APPLE. Formula: nPr =n!/(n1! n2! . . . nr!) Input parameters and values: Total number of letters in APPLE: n = 5 Distinct subsets: Subsets : A = 1; P = 2; L = 1; E = 1; Subsets' count:n1(A) = 1, n2(P) = 2, n3(L) = 1, n4(E) = 1 step 2 Apply the values extracted from the word APPLE in the (nPr) permutations equation nPr = 5!/(1! 2! 1! 1! ) = 1 x 2 x 3 x 4 x 5/{(1) (1 x 2) (1) (1)} = 120/2 = 60 nPr of word APPLE = 60 Hence, The letters of the word APPLE can be arranged in 60 distinct ways.Apart from the word APPLE, you may try different words with various lengths with or without repetition of letters to observe how it affects the nPr word permutation calculation to find how many ways the letters in the given word can be arranged. |
