 Hello and welcome to the session. In this session we will learn about power set. Now the set containing all possible the power set denoted by then power n elements. Now let's discuss one example related to power set. Let A be the set containing the elements C, O then the subsets which is denoted by 5 elements C. A set containing a single element O containing elements O, M containing elements C, M containing elements C. A set containing the possible subsets of a set A is called the power set of, so here A that is P of A is equal to set containing all the possible subsets. A set containing empty set by containing single element C, a set containing single element O, a set containing single element M, a set containing element C, O, a set containing elements O, M, a set containing elements C, O, M. Now the number of elements if number of elements power set has P raised to power n elements are 3. Therefore number of elements which is equal to 8. So now you can see that the power set of A you have learnt about power sets. So this concludes our session hope you all have enjoyed the session.
