Answer 1

Answer Choices:

Yes, P(high school ∩ GPA above 3.0) = P(high school) ⋅ P(GPA above 3.0)
No, P(high school ∩ GPA above 3.0) = P(high school) ⋅ P(GPA above 3.0)
Yes, P(high school ∩ GPA above 3.0) ≠ P(high school) ⋅ P(GPA above 3.0)
No, P(high school ∩ GPA above 3.0) ≠ P(high school) ⋅ P(GPA above 3.0)

Answer 5

I think answer should be fourth one. As, being in high school and GPA above 3.0 are dependent events. But the condition P(A ∩ B) = P(A) ⋅ P(B) is only valid for independent events.

Answer 6

Oh yeah. Sorry lol It was the last one.
