Work: Calculate the value of equation C(10,3)+C(10,4)+C(10,5)+C(10,6)+C(10,7)+C(10,8)+C(10,9)+C(10,10) .
Question type: Mathematical calculation
Solution:
C(10,3)+C(10,4)+C(10,5)+C(10,6)+C(10,7)+C(10,8)+C(10,9)+C(10,10)
=120+C(10,4)+C(10,5)+C(10,6)+C(10,7)+C(10,8)+C(10,9)+C(10,10)
=120+210+C(10,5)+C(10,6)+C(10,7)+C(10,8)+C(10,9)+C(10,10)
=120+210+252+C(10,6)+C(10,7)+C(10,8)+C(10,9)+C(10,10)
=120+210+252+210+C(10,7)+C(10,8)+C(10,9)+C(10,10)
=120+210+252+210+120+C(10,8)+C(10,9)+C(10,10)
=120+210+252+210+120+45+C(10,9)+C(10,10)
=120+210+252+210+120+45+10+C(10,10)
=120+210+252+210+120+45+10+1
=330+252+210+120+45+10+1
=582+210+120+45+10+1
=792+120+45+10+1
=912+45+10+1
=957+10+1
=967+1
=968
Answer:C(10,3)+C(10,4)+C(10,5)+C(10,6)+C(10,7)+C(10,8)+C(10,9)+C(10,10)=968
