Use the given line(s) from a random number table to select numbers to use in each problem. Select 2 contestants for a game show out of a pool of 50 46547 17395 25765 11325 14071 61688

A. 39, 25

B. 46, 47

C. 4, 6

D. 46, 25

Solution

Since it is a pool of 50 people we will have to use 2 digit numbers all less than 50 from the given random number table.

This rules out option C.

Lets write these number in vertical column

,

If we select any two digit number string at any random point then the next random number would come from two number strings lying exactly in the same position in the columns below. For first example let\'s say we select 39. The 76 is below it. Since 76 is greater than 50 we will not use this number . The next possible number would be 32. The next possible number would be 07. But 25 is not possible when the first number we have selected is 39. Hence the option A is also incorrect.

Using the same method we find that 46 17, 25, 11 , 14 can be used as random numbers. Hence the correct option is D. 46, 25
