I'm integrating something in calc and found myself with the term (5^(-x^2)). Was wondering if this needs to stay like that or I can toss it down to the denominator. It's the 2, or the z if you prefer, that confuses me. Not sure what to do about that bad boy.

So I can't find this stuff. I can find chocolate with peanut butter ripples, but not vanilla. I want vanilla damn it.

I know that it's made by at least Turkey Hill; if you know of any other companies then holler. But most importantly, do you know which stores would carry it? I've tried Giant, Safeway, and Food Lion. This is important ****. So yeah, lemme know.

Reposted out of desperation:

Find the probability that no alarm is sounded for a suitcase that has no bomb.

1 in 10000 suitcases contains a bomb.

60% of bombs makes it through security.

30% occurrence of false positives.

I would like to know what probability statement should be used with this. I'm pretty sure A (bomb in suitcase) and B (detected by security) are dependent, B dependent on A. But I might be wrong. My lack of confidence in that is part of my problem.

So basically am I looking for the probability of A and B or the probability of A given B (Or B given A...again, depends on dependency I think).

Thanks to KevinM for observing that I left out the false positives. Sorry about that. So now that the question has been revised, answers would once again be great.

Thanks. Working on an assignment due first thing tomorrow so if someone could answer this quickly I'll love you forever.

"It is said that the occurrence of false-positives in airport screenings has been about 30%. What does that mean?"

I can think of two things this could mean. Either:

1. Out of all screenings, 30% of them are false positives

2. Out of all positives, 30% of them are false

Or something else. Clarification on this would be great, thanks.
