A theater has 48 seats arranged in 8 rows of 6 seats each. three friends buy
tickets separately. what is probability they will end up in same row?
Only the number of rows matters. [The 48 and 6 are irrelevant.]

Suppose the friends are A, B and C.

 
   [Since "AND" tells us to multiply probabilities] 
 

  

[Notice that the first probability is 1 because it is certain
that A will be assigned to some row.]
