Porcellio Card ??

[Whispers]

Explain that.??It makes sense to me that if you kill x amount of monsters then you could assume your chances increased x amount of times.??I don't follow that line of logic as each monster retains its 0.03% likelihood of dropping a card; but I'm intrigued as to how someone came up with the formula which tells us how often something might happen.??

I'm not a gambling man, so such studies have never interested me.??xp

I'm going to get my high school diploma starting next week, though (dad's death seven years ago kinda forced me out of high school >_> ).??So, hopefully I'll learn all of this advanced mathematical forumulae.??I technically only have an eighth-grade education.??-_-??Though my own personal studies have - hopefully - raised my intelligence beyond that of a 13-year-old.??<_<
I do have my GED and I got *checks* 59 in the 20-80 "standard score" range and an 82 in the "percentile ranks"!??That means I did better than 82% of high school seniors according to the "Interpreting GED Test Results" info on the back of my GED.??Is it bad that a guy who didn't even finish the ninth grade did better than so many seniors???0.o

Math is my second-to-lowest score on here.??
And I always thought I was so good at math because I can do calculations really quickly in my head.??I guess computation is meaningless without proper input.??=/

[EDIT]

I get the favorable chances being complimentary to the unfavorable which would make for the 1 minus 0.9997; but what is the ^ for???I always figured it was a way of implying a number was an exponent.??If so, then how does the chance of not getting a card multiplied by itself the number of times attempted subtracted from one bring you to the probability???It sorta makes sense to me, but not completely.
Does the formula make sense to you???If so, could you explain it???It's so much easier to teach something if it makes absolute sense to you.??=3

It'll probably make sense to me by the time I wake up. Math works like that for me. I don't study it because when I sit down and think of it it makes sense. In the seventh grade I had a number of systems and formulas I made myself... Which I've now forgotten, but I had them nonetheless!
The Chance * Attempts = Probability made sense to me as you can't really test or prove it anyway. At least not in my line of belief.
