Which of the following leads to the correct mathematical solution for the number of ways that the letters of the word CAREER could be arranged to create a six-letter code?  Choose the correct choice from the following choices
A) 6!  B) 6! − (3! + 2!)  C) 6! − (3! × 2!)  D) 6!/(3! + 2!)  E) 6!/(2! × 2!)
Number of letters in word 'CAREER' = 6.   The letters 'R' and 'E' appear 2 times and 2 times respectively in the word 'CAREER'.   Therefore the mathematical solution for number of ways that the letters of the word CAR6!/(2! × 2!)6!/(2! × 2!)R can be arranged to create six-letter code   = 6!/(2!*2!)   Answer:6!/(2! × 2!)
