ki77a [65]

Answer:

125%

Step-by-step explanation:

lets just say the book is $100. 20% less would be $80
now to go back to $100, we need to add $20 to $80
20 is 25% of 80, so add the extra 25% to 100% of 80

7. The claim that started this investigation was that students majoring in engineering are more likely to be in the marching ban

Genrish500 [490]

Answer:

See explanation below.

$P(M|E) > P(M|O)$

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:

$P(M|E) =\frac{P(M and E)}{P(E)}$

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:

$P(M|O) =\frac{P(M and O)}{P(O)}$

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:

$P(M|E) > P(M|O)$
