`how many 6 letter words starting with the letter T ` T is locked into slot 1. Focus on the rest of the other slots after slot 1

yes, just change satellite's template \[\Large T \{\text{ 4 choices}\} \{\text{ 3 choices}\} \{\text{ 2 choices}\} \{\text{ 1 choice}\} L\] 4*3*2*1 = 4! = 24
mathmath333
  • mathmath333
but in book answer given isd.) none of these
jim_thompson5910
  • jim_thompson5910
then it sounds like they're allowing repetition eg: TRRAVL
mathmath333
  • mathmath333
oh
jim_thompson5910
  • jim_thompson5910
which isn't exactly fair because they didn't write that in the instructions
mathmath333
  • mathmath333
by the way i don't trust book lit has many lot of typos which made my head spin in the past lol
jim_thompson5910
  • jim_thompson5910
then go with 24 and just bring it up with the teacher

"how many 6 letter words made with T and L at the end positions from \(\color{green}{all~the~letters~of~the~word}\) TRAVEL" So no repetition.
mathmate
  • mathmate
"how many 6 letter words made with (T and L) at the end positions from all the letters of the world TRAVEL" so XXXXTL or XXXXLT
imqwerty
  • imqwerty
( ͡° ͜ʖ ͡°)

I think it should be 2*4!, which is none of the choices.
imqwerty
  • imqwerty

mathmath333
  • mathmath333
yep
mathmate
  • mathmate
Actually another hint was: "how many 6 letter words made with (T and L) at the end position\(s\) from all the letters of the world TRAVEL" the plural of the position-s confirms that both T and L are at the end.
