Answer:
103776
Explanation:
The size of the sample space is calculated using permutation. Permutation will be used because in question it is mentioned that sampling objects are sampled in order from 48 objects. The order is discussed so, the permutation is used.
nPr=n!/(n-r)!=48P3=48!/(48-3)!=48!/45!=103776
Hence the total number of objects in sample space are 103776.
