The mathematics department of a college has 15 male professors, 9 female professors, 6 male teaching assistants, and 12 female t

Vesnalui [34]

Given:

The number of male professors = 15.

The number of female professors = 9.

The number of male teaching assistants = 6.

The number of female teaching assistants = 12.

A person is selected randomly from the group.

Required:

We need to find the probability that the selected person is a professor or a male.

Explanation:

The total number of people in the group = 15+9+6+12 = 42

n(S) =The total number of people in the group

$n(S)=42$

Let A be the event that the selected person is a professor or a male.

The number of people who are professors or male = 15+9+6 = 30

n(A)= The number of people who are professors or male.

$n(A)=30$

Let P(A) be the probability that the selected person is a professor or a male.

$P(A)=\frac{n(A)}{n(S)}$ $P(A)=\frac{30}{42}$ $P(A)=\frac{15}{21}=\frac{5}{7}$

Final answer:

The probability that the selected person is a professor or a male is 5/7.

Answer: See below

Step-by-step explanation:

The transformation from triangle LMN to triangle L'M'N' is the reflection about the line y =x.

The line segment from L to y=x and the line segment from L' to line y=x are congruent.

Yes, we will get the same characteristic if we draw a line from point M to y=x and the line from M' to y=x.

It is because points P', M' and N' are reflections of points P, M, and N respectively about the line y=x.

Graph 1 (attached as first picture)

Graphing a triangle LMN and reflecting it over the line y = x to create triangle L'M'N, we have:

The transformation from triangle LMN to triangle L'M'N' is the reflection about the line y =x.

Drawing a line from point L to the line y=x and from line L' to line y=x we have:

Graph 2 (attached as second picture)

The line segment from L to y=x and the line segment from L' to line y=x are congruent.

Yes, we will get the same characteristic if we draw a line from point M to y=x and the line from M' to y=x.

It is because points P', M' and N' are reflections of points P, M, and N respectively about the line y=x.
