Question

ANGO selected 2000 families at random and surveyed them to determine number of children in a family . The data is given below

If one family is chosen at random, then match Column-I with their corresponding probabilities in

Column-II.

prove that |a b-c b+c| |a+c b c-a| |a-b b+a c| = (a+b+c) (a²+b²+c²) by property of determinants

If 2a is a+a,i.e. 2×a , then making equation adding 'x' with a in both situations

---> 2a = a+x

---> a+a = a+a

where x is any positive integer

         Then which is correct :

       (i). x+a=2×a or (ii). x+a=a+a
