e 71.5

• 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
• 6 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

  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)

• 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

• 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
