Question

need help !!!

Answer 1

We have four boxes, each of which contains ten coloured balls:

Box 1 contains 4 red balls, 5 green balls and 1 yellow ball

Box 2 contains 3 red balls, 5 green balls and 2 yellow balls

Box 3 contains 2 red balls, 5 green balls and 3 yellow balls

Box 4 contains 1 red ball, 5 green balls and 4 yellow balls

If we randomly select one ball from each box, what is the probability of selcecting exactly one red ball?


If we randomly select one ball from each box, what is the probability of selcecting at one red ball?

Answer 2

ı think (4/10)*(3/10)*(2/10)*(1/10)

Answer 3

no, the answer is 0.44

Answer 4

but im not sure how to get that answer

Answer 5

ı will think wait please

Answer 6

we use all box isnt it?

Answer 7

i guess so

Answer 8

any ideA?

Answer 9

ı dont understand question very well 4 balls will red?

Answer 10

all the balls must be red ? 4 balls ? like red red red red ?

Answer 11

\[{4\over4+5+1}\times{3\over3+5+2}\times{2\over2+5+3}\times{1\over1+5+4}=?\]

Answer 12

no, the answer is 0.44

Answer 13

of course its add up to 1

Answer 14

no wait got

Answer 15

1 ball from EACH box

Answer 16

so, P = 1red from box1 and 3no-red + 1 red from box2 and 3 no red +...

Answer 17

still dont get it

Answer 18

Okay... what's the probability of getting a red ball from ONLY the first box?
That's the product of the probability of getting a red ball from the first box and NOT getting a red ball from the other three boxes...

Answer 19

should I use bionomial probability?

Answer 20

I don't know what that is ^
(c'mon go easy on me :> )
But it seems the odds of getting a red ball from the first box is 2 out of 5
odds of NOT getting a red ball from the second box is 7 out of 10
not getting a red ball from the third : 4 out of 5
not getting a red ball from the fourth : 9 out of 10

Now just multiply these, and this'll be one of the things you add...

Answer 21

ı did the questions

Answer 22

merhaba, @honourznr
What did you get? ^.^

Answer 23

merhaba?

Answer 24

(4/10*7/10*8/10*9/10)+ (3/10*6/10*8/10*9/10)+(2/10*9/10*7/10*6/10)+(1/10*8/10*7/10*6/10)= 0.436=0.44

Answer 25

It's like "hello" only more exotic

Answer 26

:)

Answer 27

merhaba

Answer 28

Well, as long as @honourznr did the arithmetic correctly... there's no reason for it to be wrong :)

Answer 29

On second thought, maybe you need to redo that, @honourznr

Answer 30

why?

Answer 31

Okay, it's correct.. just jumbled up in the products, but correct :D

Answer 32

woww asweome what about the second one ?

Answer 33
