is there an answer choice

OpenStudy (anonymous):

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)

jagr2713 (jagr2713):

you need to calculate the probabilities involved in the four possible answer choices.

OpenStudy (anonymous):

how?

jagr2713 (jagr2713):

Look at the first possible answer. Can you find each of the two probabilities involved in Yes, P(high school | GPA above 3.0) = P(high school) ?

OpenStudy (anonymous):

um idk how

jagr2713 (jagr2713):

what answer choices can we eliminate

OpenStudy (anonymous):

idk im sorry. can u explain?

jagr2713 (jagr2713):

What is the probability that a student chosen at random from a group of 100 people is in high school? If you know how to do that, you're on the right track. If not, then it's back to basic probability calculations before you can determine whether or not events are independent or not.
