Question

The number of ways in which 5 different coloured flowers be strung in the form of a garland is :

  1. 24    
  2. 12    
  3. 16    
  4. 22    

hintHint:

T o t a l space n o. space o f space w a y s space i n space w h i c h space a space g a r l a n d space c a n space b e space m a d e space o f space n space t h i n g s space i s space fraction numerator left parenthesis n minus 1 right parenthesis factorial over denominator 2 end fraction

The correct answer is: 12



    T o t a l space n o. space o f space w a y s space i n space w h i c h space a space g a r l a n d space c a n space b e space m a d e space o f space n space t h i n g s space i s space fraction numerator left parenthesis n minus 1 right parenthesis factorial over denominator 2 end fraction

    Thus , the number of ways in which 5 different coloured flowers be strung in the form of a garland is : fraction numerator open parentheses 5 minus 1 close parentheses factorial over denominator 2 end fraction space equals space fraction numerator 4 factorial over denominator 2 end fraction space equals space 12

    The number of ways in which 17 billiard balls be arranged in a row if 7 of them are black, 6 are red, 4 are white is

    We cannot arrange the billiards balls as follows:
    There are 17 balls, so the total number of arrangements = 17!
    This is incorrect because this method is applicable only when the balls are distinct, not identical. But, in our case, all the balls of the same color are identical.

equals space n left parenthesis n minus 1 right parenthesis left parenthesis n minus 2 right parenthesis... left parenthesis n minus top enclose r minus 1 end enclose right parenthesis space space space w a y s

equals fraction numerator n factorial over denominator left parenthesis n minus r right parenthesis factorial end fraction space equals space scriptbase P subscript r end scriptbase presuperscript n

scriptbase P subscript 5 end scriptbase presuperscript 8 equals space 8 cross times 7 cross times 6 cross times 5 cross times 4 space equals space 6720 space.

    Thus we can say that the permutation concerns both the selection and the arrangement of the selected things in all possible ways.
