I wish I could stay up and work it out but I need to go to sleep. Someone will work it out for you, will check back tomorrow, if it isn't done, I will try then.

All I know is that my first answer shows how tired I am!!!! How I came up with 0% is beyond me!! I should have gone to sleep well before now! Good luck finding out the answer.

explain your answer please.....,

if there is one of each number in the hat, it can be arrived *at* in 3 turns (between the 2) by choosing either 1 or 3 first - 50% and then child 2 must choose 2 or 4 which is 66% and 50% of child 1 then choosing the correct remaining number so answer is 0.5x0.66x0.5=0.16' or roughly 17%.

I could carry on with endless scenarios :P

the combinations needed would be either 1,1,2 or 2,1,1 or 1,2,1 or 1,2,1

the odds for the first ball being picked are obviously 50% as its 2 out of the 4 balls, its is working down from there that becomes difficult.

presuming there is only 1 of each number in the hat. Since adding the lowest 3 (1+2+3=6) therefore can't happenif there is one of each number in the hat, it can be arrived *at* in 3 turns (between the 2) by choosing either 1 or 3 first - 50% and then child 2 must choose 2 or 4 which is 66% and 50% of child 1 then choosing the correct remaining number so answer is 0.5x0.66x0.5=0.16' or roughly 17%.

I could carry on with endless scenarios :P

After each child has drawn a number they return the number to the hat,

Then numbers get returned to the hat though

Me now!!

But I don't, sleep it is!!! Grrrrrrrr I am not going to be able to sleep now though, things like this annoy me!

Okay so here comes the science/statistics:

So to get it on the third go it's going to be the first childs second go so therefore the possibilities of getting 4 exactly are:

-1+3

-3+1

-2+2

So the chance of getting any particular number is 0.25 (25%) but you also have to make sure the other person dosn't pick 4 (75% chance)

So the chance for each of all these occurring is 0.25*0.25*0.75=0.046875 (4.7%) and you have three variations of getting this therefore 0.046875*3=0.140625 (14%).

Possibly.... (Unintentional probability pun)

I don't understand where your coming from here, they need to make the total of 4 in three moves exactly. So they cannot draw the numbers 4 or 3 at all otherwise they would be making too few a moves.

I bet it will be this a stupid twisted question! lol

OP doesn't even know the answer lol

I bet it will be this a stupid twisted question! lol
