Question 398228

it can be solved by two ways......


1) no. of ways to choose a president for committee = 20 
    
    no. of ways to choose 4 another members from remaining 19  = 19C4

       total no. of ways  = 20 * 19C4 

          = 77520



2) no. of ways to choose committee i.e 5 members from 20 = 20C5 

  no. of ways to select a president in a committee  = 5 

total no. of ways = 20C5 * 5  


= 77520
