-
- ans is 630.......the way is :36C2....
=36*35/2*1
=so ans is 630 - 7 years agoHelpfull: Yes(12) No(2)
- 2 can be selected out of 36
i,e. 36C2 =630 - 7 years agoHelpfull: Yes(4) No(1)
- 2 mem are selected from 36 so its a selection
36C2=360 - 7 years agoHelpfull: Yes(1) No(7)
- 36C2
so the ans is 630 - 7 years agoHelpfull: Yes(1) No(0)
- 36p2 so u will get c.1260 as answer
- 7 years agoHelpfull: Yes(1) No(1)
- ans is 630
2 students chosen from 36 ,
selection means combination
so out of 36-> 2 is selected so,
36C2=630 - 6 years agoHelpfull: Yes(1) No(0)
- answer is b 630
solution is:-
36C2=630. - 7 years agoHelpfull: Yes(0) No(0)
- 36c2=630
630 - 6 years agoHelpfull: Yes(0) No(0)
- From 36 students we have chosen 2 students ,so the combination is
36C2=630 ways. - 6 years agoHelpfull: Yes(0) No(0)
- 630---36c2
- 6 years agoHelpfull: Yes(0) No(0)
- 630
36c1*36c2=36*35/2=630 - 6 years agoHelpfull: Yes(0) No(0)
- 36c2 = 630 in the ans
- 6 years agoHelpfull: Yes(0) No(0)
- 630 is correct ans
- 6 years agoHelpfull: Yes(0) No(0)
- b 630
36 c2
36*35/1*2=630 - 6 years agoHelpfull: Yes(0) No(0)
- 630 because it is 36C2
- 5 years agoHelpfull: Yes(0) No(0)
- total ways 36*35=1260
two student have to be chosen =1260/2=630 - 5 years agoHelpfull: Yes(0) No(0)
- 36c2=36!/(36-2)!2!=630
- 5 years agoHelpfull: Yes(0) No(0)
- Answer is 36C2=630
- 5 years agoHelpfull: Yes(0) No(0)
- 36C2
as we select 2 people from 36 students that means we want to select hence for selection we use combination - 5 years agoHelpfull: Yes(0) No(0)
- 36c2=(36!)/(2!)*(36!-2!)
=630 - 5 years agoHelpfull: Yes(0) No(0)
- 36c2=630 is the ans
- 5 years agoHelpfull: Yes(0) No(0)
- 36*35/1*2=630
- 5 years agoHelpfull: Yes(0) No(0)
- out of 36 students....we have to chosen 2 montiors......so 36C2
- 5 years agoHelpfull: Yes(0) No(0)
- n(s)=36c2=630
- 5 years agoHelpfull: Yes(0) No(0)
- 36c2=36*35/2*1=630
- 5 years agoHelpfull: Yes(0) No(0)
- 36 c 2
answer is 630 - 4 years agoHelpfull: Yes(0) No(0)
- 36C2 = (36*35)/2 = 630
- 4 years agoHelpfull: Yes(0) No(0)
