Question

Another independent probability question?? Algebra 2

Answer 1

A two-way frequency table shows grades for students in college and students in high school.

Answer 2

Based on this data, are "being in high school" and "GPA above 3.0" independent events?
Yes, P(high school | GPA above 3.0) = P(high school)

Yes, P(high school | GPA above 3.0) = P(GPA above 3.0)

No, P(high school | GPA above 3.0) ≠ P(high school)

No, P(high school | GPA above 3.0) ≠ P(GPA above 3.0)

Answer 4

I am really bad with this kind of problem so i can not help sorry :(

Answer 5

now this one at least makes sense

Answer 6

It's okay, Jenna :)

Answer 7

thanks @TrixieDiVine

Answer 8

the probability that you went to high school, given that your gpa is above 3.0, is \(\frac{14}{40}\) since \(40\) total had a gpa of above 3.0 and of those 14 had high school

Answer 9

the total of the people who went to high school is 60, the total sample is 100 so the probability of high school is \(\frac{60}{100}=.6\)

Answer 10

compare \(.6\) with \(\frac{14}{40}\) and you will see that they are not equal, so the answer is DEPENDENT

Answer 11

go with
No, P(high school | GPA above 3.0) ≠ P(high school)

Answer 12

as always, it is C
the probability that it is C is \(.9\) for any multiple choice question

Answer 13

I thought that was it! :D

Answer 14

is this your last one if not mention me and i will try to help
