We want to know the probability that at least 3 developers (or more than two) from a sample of 50 are interested in Clojure, and the probability that a developer is interested in Clojure is 0.15. We can use the cdf-binomial function in Incanter (a Clojure library) to calculate that probability. I'll set the :lower-tail option to false to get the probability that more than two developers are interested (the default would tells us the probability that at most two are interested).<br /><br />(use 'incanter.stats)<br />(cdf-binomial 2 :size 50 :prob 0.15 :lower-tail false)<br /><br />Which returns 0.986, so the likelihood of getting at least three developers that are interested in Clojure from the sample of 50 is over 98% (given an assumption that 15% are interested).<br /><br />DavidUnknownhttps://www.blogger.com/profile/16790806884117432681noreply@blogger.comtag:blogger.com,1999:blog-7833979.post-90179567383904585362009-08-12T10:48:24.745-05:002009-08-12T10:48:24.745-05:00Doing Math is hard, let's compute:

I also had to use the clojure contrib library for the math power function.
