You can put this solution on YOUR website! A committee is formed by selecting 4 members from a group of 10 Republicans and 8 Democrats find the probability there is at least one member from each party on the committee
--------
P(1 <= x <= 4) = 1 - P(4 Dem or 4 Rep are chosen)
-----
= 1 - [(10C4 + 8C4)/18C4]
-----
= 1 - 0.0915
------------
= 0.9085
