Work: Calculate the value of equation (C(5,2)*C(38,2)+C(5,3)*C(38,1)+C(5,1)*C(38,3)*1)/C(43,4) .
Question type: Mathematical calculation
Solution:
(C(5,2)*C(38,2)+C(5,3)*C(38,1)+C(5,1)*C(38,3)*1)/C(43,4)
=(10*C(38,2)+C(5,3)*C(38,1)+C(5,1)*C(38,3)*1)/C(43,4)
=(10*703+C(5,3)*C(38,1)+C(5,1)*C(38,3)*1)/C(43,4)
=(10*703+10*C(38,1)+C(5,1)*C(38,3)*1)/C(43,4)
=(10*703+10*38+C(5,1)*C(38,3)*1)/C(43,4)
=(10*703+10*38+5*C(38,3)*1)/C(43,4)
=(10*703+10*38+5*8436*1)/C(43,4)
=49590/C(43,4)
=49590/123410
=0.401831
Answer:(C(5,2)*C(38,2)+C(5,3)*C(38,1)+C(5,1)*C(38,3)*1)/C(43,4)=0.401831
