To find the number of permutations of the letters a, b, and c taken three at a time, we use the formula for permutations, which is ( n! / (n - r)! ), where ( n ) is the total number of items, and ( r ) is the number of items to arrange. Here, ( n = 3 ) (the letters a, b, and c) and ( r = 3 ). Thus, the calculation is ( 3! / (3 - 3)! = 3! / 0! = 6 / 1 = 6 ). Therefore, there are 6 permutations: abc, acb, bac, bca, cab, and cba.

How many permutations are there if the letters PNRCSE are taken six at a time?
The letters in "PNRCSE" are all unique, and since there are six letters, the number of permutations of these letters taken six at a time is simply the factorial of 6. Thus, the number of permutations is 6! (6 factorial), which equals 720.

How many ways can the letters in prealgebra can arranged?
The number of permutations of the letters in PREALGEBRA is the same as the number of permutations of 10 things taken 10 at a time, which is 3,628,800. However, since the letters R, E, and A, are repeated, R=2, E=2, A=2, you must divide that by 2, and 2, and 2 (for a product of 8) to determine the number of distinctpermutations, which is 453,600.
