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?

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...

should I use bionomial probability?
PeterPan

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...

(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
