Question

a teacher assigns 10 questions for homework and wants to randomly pick 3 questions to be graded. the teacher assigns each homework question a digit from 0 to 9. refer to the given line from a random number table. which numbers represent the 3 homework questions selected? 60600 38034 99602 83440 55120 61551 6, 3, 8 6, 0, 6 6, 0, 3 6, 0, 0

Explanation:

Step1: Read the random number table

We start reading the given line \(60600\ 38034\ 99602\ 83440\ 55120\ 61551\) from left - to - right.

Step2: Select valid digits

Since the questions are numbered from \(0\) to \(9\), we ignore numbers greater than \(9\). Also, we avoid repeating the same number (if we have already selected it).

• The first digit is \(6\) (valid as \(0\leq6\leq9\)).
• The second digit is \(0\) (valid as \(0\leq0\leq9\)).
• The third digit is \(6\) (but we already have \(6\), so we skip it).
• The fourth digit is \(0\) (already have \(0\), skip).
• The fifth digit is \(3\) (valid as \(0\leq3\leq9\) and not yet selected).

Answer:

\(6,0,3\)
