[1/1 Formula]
Work: Calculate the value of equation (1-C(39-(12-1),4)/C(39,4))/(1-C(37,5)/C(40,5)) .
Question type: Mathematical calculation
Solution:
(1-C(39-(12-1),4)/C(39,4))/(1-C(37,5)/C(40,5))
=(1-C(39-11,4)/C(39,4))/(1-C(37,5)/C(40,5))
=(1-20475/C(39,4))/(1-C(37,5)/C(40,5))
=(1-20475/82251)/(1-C(37,5)/C(40,5))
=0.751067/(1-C(37,5)/C(40,5))
=0.751067/(1-435897/C(40,5))
=0.751067/(1-435897/658008)
=0.751067/0.337551
=2.225047
Answer:(1-C(39-(12-1),4)/C(39,4))/(1-C(37,5)/C(40,5))=2.225047
