Absolutely! Assuming valid hypothesis, if it's 50/50 on the initial drilling (in reality odds go up with data from each hole) 2 = 1 likely, 2 maybe, 0 maybe. 10 = 5 maybe, maybe more, maybe fewer - extremely likely to be more than 0, very likely more than 2, and so forth with possibility of 7 or 8 'good' holes having same possibility as 2 or 3.
I have seen a 1 in 66 probability NOT come up in 310+ continuously observed iterations on a lottery game in my state. I've also seen the same come up multiple times in 50 iterations.
I think as much non-drilling activity to make the odds on favorable drill hole results as favorable as they can be made has been done.
"Probability" is a very funny thing, as anyone who has gambled with deliberation can tell you.
