Answer 3

It's cool. I have one more question, though. How is the teacher in the problem using the random numbers to pick which team each student is in? It isn't clear from the problem.

Answer 4

Ummmm... I take my courses online so I can't really say... but I can just show you the textbook

Answer 5

Okay, that's exactly what I needed. This is a very odd way to create teams, but it works.

First, the teacher gives each of the ten students a unique number from 0 to 9, so all ten digits are represented by exactly one student. The order isn't important.

Second, the teacher reads the second line of random numbers, one digit at a time. If the student with that digit has not been assigned yet, the teacher assigns that student to the current team. The next student will be assigned to the other team. If the student with that digit has been assigned, the teacher skips it and reads the next one.

Using this method, all students will be assigned and each team will have five students.

Answer 6

Can you please show me that with actual numbers? It doesn't have to be from the problem although I'd prefer it.

Answer 7

Sure, I'll split up the first four students into two groups as an example.

First, the teacher reads the first digit of the second line, which is a 1. The teacher tells student #1 that he/she is on the first team.

Second, the teacher reads the second digit, which is a 4. The teacher tells student #4 that he/she is on the second team.

The teams look like this so far:
Team #1: 1
Team #2: 4

Third, the teacher reads the third digit, which is a 1. Since student #1 has been assigned already, the teacher skips it and reads the fourth digit, which is a 6. The teacher tells student #6 that he/she is on the first team.

Fourth, the teacher reads the fifth digit, which is a 4. Since student #4 has been assigned already, the teacher skips it and reads the sixth digit, which is a 1. Since student #1 has been assigned already, the teacher skips it and reads the seventh digit, which is a 5. The teacher tells student #5 that he/she is on the second team.

The teams look like this at this point:
Team #1: 1, 6
Team #2: 4, 5

Answer 8

How do i know which lines to read first?

Answer 9

The problem says that the teacher uses the second line from the random table and the example problem (Problem 2) implies that you read the digits from left to right. It's confusing, since they decided to group the digits in groups of five, but you should read them as individual numbers in this case.

Answer 10

Thank you sir, I appreciate your assistance. T:

Answer 11

You're welcome. Hopefully it makes more sense now. I know I'm still confused as to why they made it so complicated, though.
