P%28WWW%29=%284%2A4%2A4%29%2F%287%2A7%2A7%29=64%2F343,3 white balls
P%28WWR%29=%284%2A4%2A3%29%2F%287%2A7%2A7%29=48%2F343,2 white balls
P%28WRW%29=%284%2A3%2A4%29%2F%287%2A7%2A7%29=48%2F343,2 white balls
P%28WRR%29=%284%2A3%2A3%29%2F%287%2A7%2A7%29=36%2F343,1 white balls
P%28RWW%29=%283%2A4%2A4%29%2F%287%2A7%2A7%29=48%2F343,2 white balls
P%28RWR%29=%283%2A4%2A3%29%2F%287%2A7%2A7%29=36%2F343,1 white balls
P%28RRW%29=%283%2A3%2A4%29%2F%287%2A7%2A7%29=36%2F343,1 white balls
P%28RRR%29=%283%2A3%2A3%29%2F%287%2A7%2A7%29=27%2F343,0 white balls
So then
P%283W%29=64%2F343
P%282W%29=3%2848%2F343%29=144%2F343
P%281W%29=3%2836%2F343%29=108%2F343
P%280W%29=27%2F343
