Updates

I've updated my blogroll with a few more medical blogs as well as the blogs of some friends. I try to stay out of politics but both Blueollie and Freerangeathlete are primarily political but from very different perspectives, with a bit of running (or in Ollie's case walking) thrown in. Tom and Ollie are ultrarunning friends. Check out Jason's Photography Space for amazing pictures photographs. Jason is also an MD, a former colleague, but focuses on other interests in his blogging. Funny how that works.

I find it interesting that my relatively small blogroll now contains 2 female general surgeons, a female urologist and a male pediatrician. Given the respective dominance of males in surgery and females in peds, this is surprising. I'll speculate that bloggers are less conventional types, more willing to go against convention.

I don't mean to keep my blogroll "exclusive" but am always finding something else to do rather than update it. So if you feel "left out" just email me and I'll put you on with my next update (which could be a while)

Andy, the odds of NOT getting an I can be calculated this way:

(60/75)*(59/74)*(58/73)...(45/60)
and so on.

Or: (60 choose 16)/ (75 choose 16)

which is: (60!/16!44!)/(75!/16!59!) =
(60! 59!)/(44! 75!)

which in fact works out to be the same
which gives .01749795 or roughly 1.75%
as you calculated (your error is the "1-" part in your first formula; the second one is correct.

Why? The numerator represents the number of ways one can fill out 16 slots from the 60 "non-I",s and the denominator is the way of filling out 16 slots given the full 75 letter set.

Thanks, Andy.

I'm working on a post about the relative paucity of pediatrician bloggers.

Any ideas?

best,

Flea
