[1/1 Formula]
Work: Calculate the value of equation (1-C(39-(12-1),4)/C(40,5))/(1-C(37,5)/C(40,5)) .
Question type: Mathematical calculation
Solution:
(1-C(39-(12-1),4)/C(40,5))/(1-C(37,5)/C(40,5))
=(1-C(39-11,4)/C(40,5))/(1-C(37,5)/C(40,5))
=(1-20475/C(40,5))/(1-C(37,5)/C(40,5))
=(1-20475/658008)/(1-C(37,5)/C(40,5))
=0.968883/(1-C(37,5)/C(40,5))
=0.968883/(1-435897/C(40,5))
=0.968883/(1-435897/658008)
=0.968883/0.337551
=2.870331
Answer:(1-C(39-(12-1),4)/C(40,5))/(1-C(37,5)/C(40,5))=2.870331
