Four students are competing in a race. In how many different combinations could the four students place in the race?

1 answer:

4 0

"Combinations" isn't really the right word, because a combination doesn't take order of elements into account, and the outcome of a race certainly does depend on order. "Permutations" would be the correct term.

If 4 students are competing, then the race has

4! = 4 • 3 • 2 • 1 = 24

possible outcomes.

For 7/8 x 2/3 = the answer in simplest form, so we do the repricoral?

stiks02 [169]

Hello, so a simple way to do it is to cross cancel and then you would end up with 7/4 x 1/3 and it would equal 7/12 and that’s in simplest form.
