That's what im confused about too. But im pretty sure you divide by 2

Sorry, I was thinking of the dice question. The answer was C because 5,4 and 4,5 are counted as the same arent they? so you half it (i think) the 5 being the 5th person and 4 being the 4th that is.

3 is C guys, it didnt ask for how many combinations, it just asked for a 6 at least once.

Hey guys. For the flagpole question wouldnt the answer be 5? because its similar triangles, i did 4/1.5 x 3 giving me 8. then i minused that by 3 and got 5.
