in Box there are 4 slips mark e.g 1, 2, 3 , 4 .
The slips are put in a box and mixed thoroughly .
A person draws two slips , one after other , without replacement.
hence,
there are (4 × 4 - 4 ) = 12 sample space [ actually there 4 × 4 = 16 sample space but 4 are additional sample space e.g {(1,1),(2,2),(3,3),(4,4)}]
e.g., S = {(1,2),(1,3),(1,4),(2,1),,(2,3),(2,4),(3,1),(3,2),(3,4),(4,1),(4,2),(4,3)}
