Question 565523
A fast food restaurant gives away a toy with each children's meal. There are 4 different toys given away randomly. How many meals will the family have to buy to get all 4 toys? 
What is the probability involved? (I think it is (1/4)^4 or 1/256, but am I wrong? Is it 4C1 or 1/6?) 
Would the family have to buy 4! meals?

Comment: There is no answer to that question.
Cheers,
