Which of the following leads to the correct mathematical solution for the number of ways that the letters of the word ELECTRIC could be arranged to create a eight-letter code?	Select the correct option.
A) 6!	B) 6! − (3! + 2!)	C) 6! − (3! × 2!)	D) 8!/(2! x 2!)	E) 9!/(3! × 2!)
Number of letters in word 'ELECTRIC' = 8.   The letters 'E' and 'C' appear 2 times and 2 times respectively in the word 'ELECTRIC'.   Therefore the mathematical solution for number of ways that the letters of the word ELECTRIC can be arranged to create eight-letter code   = 8!/(2!*2!)   Answer:8!/(2! x 2!)
