The total number of ways in which a selection(one or more) can be made of `p+q+r` things of which p are all alike, q all alike, r all alike is `( p + 1 ) ( q + 1 ) ( r + 1 )-1` II: The number of permutations of 'n' things taken together when 'p' of the things are alike of one kind, 'q' of them alike of a second kind, 'r' of them alike of a third kind and the rest all different is `(n!)/(p!q!r!3!)` Which of the above statement is true?
