The other possibilities include that she chooses at least one book that is not a mystery; this means the complement is not choosing all mysteries.
<h3>What is the probability?</h3>
Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.
The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.
P(E) = Number of favorable outcomes / total number of outcomes
Mariah is randomly choosing three books to read from the following: 5 mysteries, 7 biographies, and 8 science fiction novels.
The complement of an event is the remaining possibilities.
Our event is Mariah choosing 3 mysteries.
The other possibilities include that she chooses at least one book that is not a mystery; this means the complement is not choosing all mysteries.

Answer:
The answer is B.
Step-by-step explanation:
That's because in A. angle S and angle Z aren't corresponding in the congruence of RST and XYZ.
In C. line RS and line ST can' be proven to be congruent because they arent a part of the what we know which is RST is congruent to XYZ. It says nothing about RS being congruent to ST.
And D. has the same problem as A. with the line ST and line XZ not corresponding the what we know. If it had said ST is congruent to YZ, or that RT is congruent to XZ then it would be true. Because RST is congruent to XYZ. And R corresponds to X, S corresponds to Y, and T corresponds to Z.
So B. would be the answer because R and X correspond to one another because it's written as RST ans XYZ and both R and X are the first letters represented in both triangles.
Answer:
Step-by-step explanation:
7x-11=4x+4(being vertically opposite angles)
7x-4x=4+11
3x=15
x=15/3
x=5
angle 2+angle1=180 degree(being straight line)
7x-11+angle 1=180
7*5-11+angle 1=180
35-11+angle1=180
24+angle 1=180
angle 1=180-24
angle 1=156 degree
