A is a set containing \( n \) elements. A subset \( S_{1} \) of \( A \) is chosen. The set \( A \) is reconstructed by replacing the elements of \( S_{1} \). Again, a subset \( S_{2} \) of \( A \) is chosen and again the set is reconstructed by replacing the elements of \( S_{2} \). The number of ways of choosing \( S_{1} \) or \( S_{2} \) where \( S_{1} \) and \( S_{2} \) have one element common ishttps://bit.ly/YTAI_PWAP https://www.pw.live
