PLUS ONE MATHEMATICS CHAPTER 1 IMPORTANT POINTS

  4 mark quetion

  1. IF A ={a,b,c } .then write power set of p (A)

                                                      n

      (a) collection of  all subset  , 2(n means how many elements  have on this set ) 

                      n  3

          when 2=2   =8.    so how many elements have on this power set answer is 8.and it have                        {a,b,c}  8 subset 

 2. if the number of subset with two elements of a set P is 10 find the total number of elements

    in set (P)

     (a)  number of elements in P =5 

          P= {1,2,3,4,5,} ={1,2}1,3}{1,4}{1,5}{2,3}{2,4}{2,5}{3,4}{{3,5}{4,5}

      

         n(P) =5    10

 3. find the number of elements in he power set of P
                        n       5
   (p) n(p(A)=2    2=     32 (total 32 elements)


3.consider venn diagram of the universal set
    u{1,2,3,4,5,6,7,........13
