If there is 10 numbers and 26 letters there is 1/36^3 = 1/46656 probability that your favorite sequence will be displayed.
If you repeat clicking on a captcha long enough you will find one of your favorite sequences. If there are n funny 3-word numbers chances that you will roll one of them is:
1-(1-1/46656)^n. So if there are 40 funny sequences (remember soy can be written as s0y, 5oy, 50y) then after 2000 captcha generations chances that you'll roll something is ~88%.

>>673423I got another 'dea. You can estimate how many of all 3-letter-number sequences have some meaning for you. I rolled cmp (cpp function), joz, ku7 and 5 more sequences in ~50 rolls.
