Answer 1

how can i know if it is independent or dependent @satellite73

Answer 2

yes

Answer 3

if \[P(A|B)=\frac{P(A\cap B)}{P(B)}=P(A)\] then they are "independent"
compare \[\frac{P(A\cap B)}{P(B)}\] with \(P(A)\) if they are equal, then independent

Answer 4

i got 1/4

Answer 5

yeah me too, you mean for \(\frac{P(A\cap B)}{P(B)}\) right?

Answer 6

so 25% is not 10% right?

Answer 7

right

Answer 8

therefore NOT independent, which actually means "dependent"

Answer 9

ok thank you :)

Answer 10

yw

Answer 11

so that would be dependent for a right?

Answer 12

not sure what you mean "for a"

Answer 13

for P(A)

Answer 14

ok hold on

Answer 15

or just for A?

Answer 16

you do not call probabilities independent ore dependent, only sets
right
BUT you cannot say as set A in independent, that doesn't mean anything
you say A and B are independent or A and B are dependent

Answer 17

oh ok so in this case A and B are dependent then
thank you :)

Answer 18

Answer 19

I did them all and I got that none is independent is that correct?
