Question

a jury pool consists of 50 potential jurors in how many ways can a jury of 12 be selected

Answer 1

Here we have to choose any 12 out of 50

here order of choosing jury does not matter it is only a group of 12 people we have to make

We know when we have to choose any r articles out of total n articles we can choose it in total ncr ways where c is a combination formula

ncr= n! / ( r! * ( n-r)!) (" ! " is factorial operation )

we have to find out 50 C12 = 50 ! /( 12 ! * ( 50-12)!) = 121399651100
