Question 5

3 pts
In a table of random digits such as Table B (in your textbook), each
digit is equally likely to be 0, 1, 2, 3, 4, 5, 6, 7, 8, or 9. What is the
probability that a randomly chosen digit in the table is between 5
and 8 (inclusive)?
1/5
4/9

Answer 1

`(4)/(9)`

Explanation:

To find this probability, we have to know:

• How many numbers are there in between 5 and 8 inclusive?
• How many total numbers are there?

We simply divide the first answer by the second one and get our probability.

So, the numbers are 5,6,7,8 ----- that is 4 numbers

How many numbers are there in total? That is:

0, 1, 2, 3, 4, 5, 6, 7, 8, or 9 ------- 9 numbers

Thus, the probability is 4/9
