Answer 3

HI!!

Answer 4

hello!

Answer 5

What do you think is the probability?

Answer 6

And I'm not sure, I tried doing 575/650 and 300/650, but it's not working out

Answer 7

\[P(F|B)\] you can read off of the table

Answer 8

total on the bus is what?

Answer 9

What do you think is the probability?

Answer 10

the total on the bus is 650

Answer 11

ok, and in that column, how many females were on the bus?

Answer 12

300

Answer 13

ok so \[P(F|B)=\frac{300}{650}\]which i am sure you can reduce

Answer 14

now on to see if the events are "independent" or "dependent"

Answer 15

how many students total?

Answer 16

i tried reducing by 5 and i got 12/26, which isn't an answer choice

Answer 17

we are not done yet

Answer 18

oh, ok

Answer 19

what would i do next

Answer 20

oh wait, you reduced wrong !!

Answer 21

\[\frac{300}{650}=\frac{30}{65}\]is a good first step,
now divide top and bottom by 5

Answer 22

what do you get?

Answer 23

ok, 6/13

Answer 24

sorry, my computer is lagging

Answer 25

so A or C
now we need \(P(F)\)

Answer 26

how many total female, how many total students?

Answer 27

total female is 575, total student is 1200

Answer 28

so \[P(F)=\frac{575}{1200}\]which is NOT the same as \(P(F|B)\)

Answer 29

they would be dependent because when reduced, they arent equal

Answer 30

so A?

Answer 31

so the events are dependent, yes, what you said

Answer 32

Thank you so much!
