7th grade math questions help me!!!!!!!!!!!?

Now, for your first problem, here’s how you organize it.

Let’s say you are A and your three friends are B, C, and D. The fifth person in the pool would be E. This is a small enough number that you could actually write down all the possible combinations. (You could mix up the letters, but the team would be the same regardless of what order they are chosen in.)

ABCD

ABCE

ACDE

BCDE

Out of the four possible teams that could be picked, only one includes you and your three friends. So now can you see what is the probability that A, B, C and D will be on the same team?

In the second one, you need to know what percentage 132 is of 300. You can use a calculator to find out what is 132 divided by 300. Then multiply that percentage times 1000 to find out how many customers will probably order a salad. To check and make sure that your answer makes sense, realize that 132 is under half of 300, so the right answer will be under half of 1000.
