A group of people in an art class and a crafts class were surveyed whether they exercise more than 5 hours a week or less than 5

hours a week. In the art class, 5 people exercise more than 5 hours a week and 8 people exercise less than 5 hours a week. In the crafts class, 10 people exercise more than 5 hours a week and 4 people exercise less than 5 hours a week.
What is the relative frequency of people who exercise more than 5 hours a week in the art class to the total number of people surveyed?

The Relative Frequency is how often something happens out of all possible outcomes. Here you have numbers -- Arts - 5 more, 8 less Crafts- 10 more, 4 less ------------------- What is the relative frequency of people who exercise more than 5 hours a week in Arts class? There are 5 people in arts that exercise more than 5 hours/week. The total number of people all together surveyed is 5 + 8 + 10 + 4 = 27 people There are 5 out of 27 people that are in this catagory Relative Frequency = 5/27 = 0.19

How many integers from 1 through 100,000 contain the digit 6 exactly once?
wariber [46]
Consider the set of all (not-all-zero) decimal strings of length 6. This is the set of strings


000001
000002
...
099998
099999
100000

There are obviously 100,000 strings in this set, so we have a one-to-one correspondence to the integers between 1 and 100,000. Think of any string starting with 0s as the number with the leading 0s chopped off.

There are two choices for the first digit, either 0 or 1, but a number can only contain a 6 if the first digit is 0; otherwise, the number would exceed 100,000. For every digits place afterward, if a given digits place contains a 6, then the remaining four places have 9 possible choices each, choosing from 0-9 excluding 6. If we fix the 6 in, say, the second digits place, then the number of integers between 1 and 100,000 containing exactly one 6 is


1\cdot1\cdot9^4=6561


where the first 1 refers to the only choice of 0 in the first digits place, the second 1 refers to the unique 6 in the next place, and the remaining four places are filled with one of 9 possible choices.


Now, notice that we can permute the digits of such a number in 5 possible ways. That is, there are 5 choices for the placement of the 6 in the number, so we multiply this count by 5.

5(1\cdot1\cdot9^4)=32,805
