Well to find the mean you need to add up the total number of people and then divide by the total number of days meaning if there is a total of 105 people, you would divide that by 5 and get 21

13 + 23 + 24 + 31 + 14 = 105

105 / 5 = 21

Using the Fundamental Counting Theorem, it is found that you have 55 different choices with this brand.

Fundamental counting theorem:

States that if there are n things, each with $n_1, n_2, …, n_n$ ways to be done, each thing independent of the other, the number of ways they can be done is:

$N = n_1 \times n_2 \times \cdots \times n_n$

In this problem:

There are 11 colors available, hence $n_1 = 11$ .

There are 5 writing tips available, hence $n_2 = 5$ .

Then:

$N = n_1 \times n_2 = 11 \times 5 = 55$

You have 55 different choices with this brand.

250 people attended the first showing of a play. Of the 250, 75 were adults above the age of 40, 50 were between the ages of 20

HACTEHA [7]

The answer is D) 40% because when you add the people who were already accounted for, it comes to 150, which is 60% of 250. So the remaining attendees, children 12 and under, makes up the rest of the 250, which was 40%.
