Question

a teacher wanted to fairly choose three students from a class of 28 to raise the schools flag. she assigned each student a two - digit number from 01 to 28. (lets consider \01\, \02\, etc. to be two - digit numbers.) she then selected the following line from a random number table. 77048 94517 97444 59947 16936 39384 97551 starting from the left, she used the line above to form two - digit numbers as follows. 77 04 89... using this new list and starting from the left, she chose three two - digit numbers from 01 to 28. she skipped numbers she had already chosen, the number 00, and numbers greater than 28. the students who were assigned these two - digit numbers were chosen. which three students did the teacher choose? student student student

Explanation:

Step1: Analyze the first two - digit number

The first two - digit number from the left in the new list is 77. Since 77>28, we skip it.

Step2: Analyze the second two - digit number

The second two - digit number is 04. Since 1≤04≤28, this is the first selected number.

Step3: Analyze the third two - digit number

The third two - digit number is 89. Since 89>28, we skip it.

Step4: Continue analyzing numbers

Moving on, we get more two - digit numbers. The next valid number (within 1 - 28 and not already chosen) is found. Let's continue checking the remaining numbers in the list. The next valid number is 16 (as it is between 1 and 28 and not previously chosen).

Step5: Find the third number

Continuing to check the list, we find the next valid number which is 23 (between 1 and 28, not previously chosen).

Answer:

Student 04, Student 16, Student 23
