 Hi and welcome to the session. I'm Priyanka and let us do the question. It says how many elements has P of a if a is equal to 5 Wait, so let's start with our solution Now we are given that a is equal to 5 and we need to find P of a So power set is a set Containing all possible Subsets so first of all let us write down the subset of this null set as we know that there is only One subset of this sets that will be Phi itself so we can say that the number of elements of Power set a is One so the answer is P of a has one Element in it right so this completes the question that was given to us in this We need to tell how many elements was there in set a and we have written it, right? So this completes bye for now
