P%28R%2CR%29=%2826%2F52%29%2825%2F51%29=25%2F102

P%283R%2CB%29=52%2F833%2B+52%2F833%2B52%2F833%2B52%2F833
P%283R%2CB%29=208%2F833

1-8:
1,3,5,7 - Odd
2,4,6,8 - Even
8 total.
P%28even%29=4%2F8=1%2F2
.
.
.
P%28PPV%29=P%28PPV%29%2BP%28PVP%29%2BP%28VPP%29

P%28PPV%29=3%2F55
.
P%28OOP%29=P%28OOP%29%2BP%28OPO%29%2BP%28POO%29

P%28OOP%29=3%2F22
So then,
P=P%28PPV%29%2BP%28OOP%29
P=3%2F55%2B3%2F22
P=21%2F110
