How do i do part c? the answers r next to the qView attachment 42962
for i), group E_E, where _ is any other letter.
firstly there are 5 places to put the E_E (draw it out to see why)
then, there are 5! ways to put the other 5 letters
so in total there are 5 x 5! ways

similar idea for the others, you just need to draw it out to determine how many places you can put the E's (there are 4 for E__E, 3 for E___E, 2 for E____E, 1 for E_____E) then multiply by 5! for placing the remaining letters
