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))
=1-1724814000/(C(40,5)*C(39,4))
=1-1724814000/(658008*C(39,4))
=1-1724814000/(658008*82251)
=1-1724814000/54121816008
=1-0.031869
=0.968131
Answer:1-(C(40-12,5)*C(39-12,4))/(C(40,5)*C(39,4))=0.968131
