What would happen if two black holes came into contact with each other?

So in Mexico right now it's 70 degrees. In illinois it's 36 degrees. We are on the same vertical axis, and the sun is still facing us from the same direction, as we are perpendicular on the face of the earth.

Since the sun is 90,000,000 miles away, and so much larger than earth, how does a 1,000 or so mile difference, create vast temperature differences in our atmosphere?

Does vinegar neutralize dish soap ?

Posted: 23 Dec 2016 10:07 AM PST

I have heard that the combination of dish soap and vinegar is a great household cleaner. However , doesn't the acidity of the vinegar just neutralize the dish soap since it is a base?

What's the average number of attempts necessary to reach 1,000 successes at a 1% rate?

Posted: 23 Dec 2016 08:47 PM PST

So in statistics I understand that, given a 1% chance of success, it will take an average of 68.something attempts to succeed, because the equation is .99^x = .5 and you solve for x. However, does that mean that the average attempts to get, say, 1,000 successes at a 1% rate would be ~68,000? On one hand, it makes sense that you would just multiply the average attempts by the number of successes necessary. However, looking at it from the standpoint of common sense, a 1/100 chance times 1,000 necessary successes should just be 100*1,000. Which number is correct (if either) and why?

Thanks in advance!

Edit: for further clarification, I'm basically asking a question that's an extension of this old Reddit post. If .99¹⁰⁰ = X and X is about .64, then you can just substitute X for number of attempts instead of probability and thus find the average number of attempts in order to have any given chance of success, correct? That is, .99^x = .5, so x =68.9676. This seems to assert that, after about 69 attempts, you would have a 50% chance of success. So why doesn't that translate into chance of having a certain number of successes within a certain number of attempts? Or why is this number not 100, since intuitively it should take an average of 100 attempts to succeed given a 1% chance of success?

Is IBD a genetic disease?

Posted: 22 Dec 2016 09:24 PM PST

I've been trying to google it and find an answer but no, I haven't been able to find a clear answer

So are Chron's Disease and Ulcerative Collitis genetic in origin? Like, can someone without genes develop either of them?
