what is the number of possibilities of arrangements of the letters in the word intercept?
When there is no repetition of the letters, the number of permutations (order counts) is nPr, taking r letters at a time n!/(n-r)!.
If all n letters are taken (as in the present case) to make the word, nPn reduces to
n!/(n-n)!=n!/0!=n!/1 = n!
However, if there are repetitions of letters, we have to reduce the number of permutations by the factor r1! for each occurrence of the duplication/repetition.
Examples:
1. How many arrangements of the six letters of the word "number" are there?
6 letters, no repetitions, 6P6=6!=720.
2. How many arrangements of the eleven letters of the word "mathematics" are there?
We note repetitions of the letters m(2), a(2), t(2), so the number of arrangements
= (11P11)/(2!2!2!)
=11!/(2!2!2!)
=4989600

To find the number of possibilities of arrangements of the letters in the word "intercept," you can use the concept of permutations. A permutation is an ordered arrangement of objects. In this case, we are arranging the letters in the word "intercept."
The word "intercept" consists of 9 letters. To calculate the number of arrangements, we need to determine the total number of permutations, which can be found using the formula:
\(n!\)
Where \(n\) represents the number of objects (in this case, the number of letters).
In our case, \(n = 9\) because there are 9 letters in the word "intercept." Hence, we can substitute the value into the formula and calculate:
\(9! = 9 \times 8 \times 7 \times 6 \times 5 \times 4 \times 3 \times 2 \times 1 = 362,880\)
So, there are 362,880 possible arrangements of the letters in the word "intercept".
