Step-by-step explanation:
Notation
First we need to define the following events:
E = The student is in a major of enginnering
O= The student is in a major different from enfinnering
M= The student is in the marching band
Solution for the problem
For this case we can calculate the following probability:

And that represent the following event: "Given a randomly selected student is an engineering major, what is the probability the student is in the marching band"
And the probability that need to calculate to compare is this one:

And that represent the following event: "Given a randomly selected student is NOT an engineering major, what is the probability the student is in the marching band"
And if the claim is satisfied we need to see this:

Answer:
Step-by-step explanation:
45+8x+21+90=180 degree(sum of interior angles of a triangle)
156+8x=180
8x=180-156
8x=24
x=24/8
x=3
Answer:
x= -3/4 or x= 0.75
