Question

Fifty students in the third grade class listed their hair and eye colors in the table below:

Brown hair Blonde hair Total
Blue eyes 14 8 22
Brown eyes 16 12 28
39 20 50

Are the events "blonde hair" and "blue eyes" independent?
Yes, P(blonde hair) • P(blue eyes) = P(blonde hair ∩ blue eyes)

Yes, P(blonde hair) • P(blue eyes) ≠ P(blonde hair ∩ blue eyes)

No, P(blonde hair) • P(blue eyes) = P(blonde hair ∩ blue eyes)

No, P(blonde hair) • P(blue eyes) ≠ P(blonde hair ∩ blue eyes)

Answer 1

@aum

Answer 2

Answer 5

So what is the final answer

Answer 6

please do not ask for a final answer, we approach a solution .. we dont just hand out solutions

Answer 7

no I know the answer I just checking my work

Answer 8

since we are comparing blond and blue:

Brown hair Blonde hair Total
Blue eyes 14 [8] 22
Brown eyes 16 12 28
39 20 50

does 8/22 = 20/50?

Answer 9

50(8) = 22(20)

400 = not 400

looks like its no becuase not equal to me

Answer 10

So the last answer choice correct as I chosen previously

Answer 11

Answer 12

So it is the last choice thanks
