FINITE people HELP me out pleaz!
 

How many 3-digit natural numbers have no 5's but at least one 6 ?

72 i believe

You trying to blow people's minds with that kinda question?

Where's Colin when you need him? I bet he has some formula memorized to figure that question out.

no not 72

i have a paper with answers

but they are in different order and there is no 72 on it :(

this is simple factorials..but i dont fucking understand it lol

24,735

Is this some kinda code question for the special people?

dammnit, im too fucking tired for this.....one more try.

ahhaah special people :glugglug

234 is my final answer

it is either 220 or 200 lol

but i can not figure it out..

It seems that you're missing the obvious instances of
160
161
162
163
164
166
167
168
169

260
261
262
etc...

100 through 200 there are 17 instances.
200 through 300 there are 17 instances.
300 through 400 there are 17 instances.
400 through 499 there are 17 instances.
600 through 700 there are 81 instances.
700 through 800 there are 17 instances.
800 through 900 there are 17 instances.
900 through 999 there are 17 instances.

200 is right

final answer be dammned!!!

thanks man!!! :)

how about this one:

How many natural numbers less than 100000 have at least one digit repeated?

np
:sleep

:GFYBand

oh lord, i think my brain is saying no to this one :ugone2far

:1orglaugh

anyone else? :hi

67510, sorry had too much free time I guess, the mirc script below will save you time though, even if it does take close to a minute. :glugglug

alias weird.thing {
set %repeats 0
set %start.from 0
while (%start.from <= 100000) {
echo -a progress %start.from
if ($count(%start.from,0) >= 2) { inc %repeats | goto end }
if ($count(%start.from,1) >= 2) { inc %repeats | goto end }
if ($count(%start.from,2) >= 2) { inc %repeats | goto end }
if ($count(%start.from,3) >= 2) { inc %repeats | goto end }
if ($count(%start.from,4) >= 2) { inc %repeats | goto end }
if ($count(%start.from,5) >= 2) { inc %repeats | goto end }
if ($count(%start.from,6) >= 2) { inc %repeats | goto end }
if ($count(%start.from,7) >= 2) { inc %repeats | goto end }
if ($count(%start.from,8) >= 2) { inc %repeats | goto end }
if ($count(%start.from,9) >= 2) { inc %repeats | goto end }
:end
inc %start.from
}
}
