Answer 1

@misty1212 halp

Answer 2

i am not sure exactly what it is asking in terms of "outcome" but you can think of this just like flipping a coin 5 times

Answer 3

idk either

Answer 4

@SolomonZelman do you know?

Answer 5

no, not really. Sorry that can't help

Answer 6

aww

Answer 7

I am sure there are many users who know this math better than me though...

Answer 8

goog luck

Answer 9

it is not really too clear is it? we can try it though

Answer 10

lets say we get a white ball on the first try
then the probability you get a white ball on the second try is 1/2

Answer 11

i messaged my teacher that it didn't make sense, maybe she can cut me some slack

Answer 12

not clear what happens on the third draw though
if you get a white then black then black does that count as getting the same as the previous one?

Answer 13

what is considered a "game"?

when you get a different outcome, does that end the game?

Answer 14

i dunno

Answer 15

anyway @misty1212 is right in that each outcome has chance of 1/2 since there are only 2 balls

prob of scoring "-2" or "2" is both 1/2

Answer 16

For 3rd draw, its 2 successive 1/2 chances ----> 1/2*1/2 = 1/4

there is 1/4 chance of getting 3 in a row or getting 2 in row then different

Answer 17

and so on ...

1/8 chance of getting 4 in row

1/16 chance of getting 5 in row

Answer 18

heres a tree diagram to help
