Hello there,
If somebody could assist me with this question I'd be very appreciative:
"How many ways are there to arrange the letters:"
1) SEARCH
2) FORMULAE
3) HOROSCOPES
4) DIFFERENTIATE
Am I right in thinking the answers are:
1) 6! / 1!
2) 8! / 1!
3) 10! / (3!2!) - taking the duplicate o's and duplicate s's as factorials in order
4) 13! / (3!2!2!) - taking duplicate e's, f's and i's as factorials in order
Also, are those answers in the format required or would numerical answers be suited? It's been a while so apologies for any obvious mistakes or misunderstandings.
Regards,
