Work: Calculate the value of equation 1-C(40-12,5)*C(39-12,4)/C(40,5)*C(39,4) .
Question type: Mathematical calculation
Solution:
1-C(40-12,5)*C(39-12,4)/C(40,5)*C(39,4)
=1-98280*C(39-12,4)/C(40,5)*C(39,4)
=1-98280*17550/C(40,5)*C(39,4)
=1-98280*17550/658008*C(39,4)
=1-98280*17550/658008*82251
=1-1724814000/658008*82251
=1-2621.266003*82251
=1-215601750.012753
=-215601749.012753
Answer:1-C(40-12,5)*C(39-12,4)/C(40,5)*C(39,4)=-215601749.012753
