A= {1,2,{3,4},5}
Sir, are {1,2,5} subsets of set A?
Are they elements (belongs to)?
Dear student,
The formula to find the number of sub sets is (2^n) - 1
The formula to find the number of sub sets is (2^n) - 1
n being the number of elements, {-1 to eliminate the null set}
2 power 5 is 2 X 2 X 2 X 2 X 2 = 32
32–1 = 31.
Yes, (1,2,5) are subsets of set A (1,2,(3,4),5)
