Re: Q8
The percentage chance that a backdoor flush will come in is 10/47 * 9/46 ~= 0.04163 or 4.1%
The formula relating number of outs (on the flop) to percentage chance of hitting (by the river, which is the only way to get a backdoor flush) is:
%chance = N(93 - N)/2162
Where N is equal to the number of outs.
Solving for N in this equation will give one the number of outs a backdoor flush is equivalent to. With the given numbers, one gets that a backdoor flush is equal to about 0.9780 outs. Since this isn't the nut flush though it is worth even less than that. Take what you will from these calculations, I just wanted to clear it up.
