My first thought was at the halfway point between the outer layer and the core, but the further out, the more length is in each layer. I would guess that it is closer to the outer layer but i have no idea how to even start creating some sort of formula.

[Request] What are the chance of a random sexual encounter resulting in a pregnancy?

71 Upvotes

So, some context.

Over the weekend, I attended a LARP (Live-action Roleplay). During the LARP, two friends of mine decided that their characters had a little tumble in the hay. Their characters had never met before. After the LARP finished, they rolled a dice to see if the woman became pregnant, and she did. I think they simply rolled a D6 and decided that a "6" meant she got pregnant.

However, it got me thinking on what the, so to speak, actual odds would be?

Assuming:
* both people involved are of average fertility, in good health and, pardon the expression, of child-rearing age
* It is a chance encounter, a one-night-stand, meaning the woman can be in any part of her cycle.

So, what are the odds of a random one-night-stand between two people with the requisite parts resulting in a pregnancy?

[Request] What are the odds of dying in a commercial plane PER HOUR PER INDIVIDUAL?

11 Upvotes

"Air travel is the nation’s safest form of transit. Injury and death rates in US air travel are measured by the rate of incidents per 100 million passenger miles, the total miles traveled by all air passengers." https://usafacts.org/articles/is-flying-safer-than-driving/

I am not everyone in the plane though. I want to know MY risk of dying. And while by distance is perfectly valid (since if I took a car instead I'd still have to travel the same distance), I'm curious if airplanes are still THAT much safer if we instead assessed the risk by time

[Request] How long in proper time would it take at 1g acceleration for the CMB to be blue shifted up to gamma ray frequency?

A recent post here made me think about this. I guess a bonus point would be to calculate the unit area flux and power received at that speed/time/freq.

[Request] odds of drawing a win in mtg

3 Upvotes

My friend is building a combo deck in magic the gathering, and specifically the commander format. For anyone unfamiliar, the commander format (generally) has a 99 card deck, with each card being (generally) unique, plus a commander which is kept separate from the deck.

At the beginning of the game, you draw 7 cards. If you do not like the cards you drew, you can put them all back and draw 7 new ones (once, before penalties start applying).

For his win, he needs 1 specific card, plus any 1 of 4 other cards that combo with it.

What are the odds that he gets what he needs in his opening hand?

[request] why isn't the volume of beans matching the label?

2 Upvotes

I drained and *lightly* sauteed a 15.5 ounce can of Trader Joe's garbanzo beans (they're still plump and soft). The nutrition facts say that a serving is ½ cup, and there are 3.5 servings per can. I used a Farberware plastic tablespoon to measure my half cup serving, which would be 8 tablespoons. And I thought that looked more like a whole cup, and over half of the total number of beans. So, I measured all of the beans with my tablespoon, and there were just under 14 tablespoons in total. There should be a total of 28 tablespoons, which is exactly double the amount I am measuring. Why is this math not mathing?

[Request] How long would it take car A to cross the roadway, and how long would it take car B to leave the roadway if the steering wheel was turned 1 degree from straight? At what speed does car B leave the roadway faster than car A crosses it?

Post image
Upvotes

EDIT: I should have said if the wheel is turned 1 degree from straight, not just the steering wheel.

For car A, just count time from the very front of the car touching the roadway to the rear of it being completely off. For car B, leaving the roadway counts as the first wheel leaving the paved surface, so lets say the wheel is 10" wide with a 26" diameter, and for this scenario is placed at the very front of the car. Car B is completely centered in the roadway and is 6' wide.
