The answer would be-2 and 5
Ok 12 eggs in 1 dozen.
Half of 12 is 6, now you need to do half of that, which is equal to 1/4 and that is 3.
There are 3 eggs in 1/4 dozen of eggs
1/12 chance
You have 4 counters and want a red (1/4) then a white, but don't replace any which gives you (1/3) *since you don't replace the other one...* Then you multiply the two (1/4*1/3) and you should get 1/12.
There will be 78 hats in total
Is that what you mean't?
