As many said: whatever you rolled before, the next roll will always have a 1/6 chance of becoming any specifuc number. There's 6 different outcomes, each is equally likely.

I'd like to add: When figuring out the probability of the sum of multiple rolls, you look at the number of combinations that make that sum.

There's only one way to make a 2 with 2 rolls (1 and 1).

There are two ways of making a total of 3: 1+2 or 2+1

There are three ways of making a total of 4: 1+3, 3+1, 2+2

5 = 1+4, 4+1, 2+3 or 3+2

And so on.

The probability of a certain sum (12 for two sixes) is the number of combinations that give you that sum (1) divided by the total number of combinations there are (6*6), so it would be 1/36.

If you wanted another specific outcome, say the first die must be a 3 and the secomd one must be a 1, that's also 1/36. If the sum just has to be 4 the probability is 3/36 or 1/12.

Once the brake locks the wheel (or ABS comes on), that is the limit of traction between tire and ground. Engine braking has to go through the tires (it doesn't brake by increasing air drag or anything). Since any modern car brake system has enough power to lock the wheels, engine braking does not slow down the car any faster than simply slamming on the brakes (with ABS) or threshold braking (non ABS).

If you are noticeably slowing down the car more through engine braking while applying FULL pressure on the brakes - your brakes are likely defective.

If you live in the states, then that is probably true since most manual drivers tend to be somewhat enthusiastic about cars over there. But a majority of all manual drivers don't live in the US.

Here in Europe, a vast majority of cars were manual still a few years back (still are I think, but almost all new cars are auto nowadays), which meant that everyone including your wife and granny (literally) were driving manuals. Which means that most manual drivers were the type of people who see cars as a mandatory but boring appliance. These people don't know how to rev match, let alone heel-toe.

The marketing component is big. Getting the game talked about in the spaces that potential customers frequent is hugely important but also requires a lot of resources and connections that developers don't often have. It's not just paid ads but trailers, criticism, launch events, merch, engagement from Twitch streamers, and all the other pieces of the hype engine. The difference between all the good games you've never played and all the mediocre games you have played is mostly marketing.

Also, like book or music publishers, video game publishers may also advance some money to the developers to fund the development of the game, working essentially as venture capital.

It's actually not hard to get out of jury duty--especially if you are an engineer or other sciency type (or a lawyer). Lawyers don't like people who will use their own experiences and knowledge in interpreting evidence. They also fear that they may influence others with their external knowledge of things.

Lawyers want people to buy their half truths, and if they think you're not as susceptible they won't want you anywhere near the jury.

People accused of crimes have a right to have their fate decided by a team of normal people. And normal people have better things to do than decide the fate of someone accused of a crime, so we wouldn't be able to fulfill that right if we didn't make it hard to get out of.

Because they are independent events.

Think of it this way - if you roll a die in Chicago and I roll a die in New York - they are not connected in any way. Agree?

Same is true if you roll the same die repeatedly in the same place. It has no memory.

It is possible to design a system that tries to balance outcomes explicitly so as to “load share” based on some memory but that is not how ordinary randomness works.

This is why in engineering you learn that pounds can be either a force or a mass, designated lbm or lbf. Pounds mass is based around the gravitational constant only, so it is a weight but because the gravitation constant is standardized it can also be a form of mass. Pounds force accounts for the gravitational constant where the object physically is or needs to be studied. For earth, pounds mass and pounds force are the same. Anywhere else, they will differ.

​

Edit: For those who don't know, a slug is the actual imperial unit of mass

I think anyone who has driven a manual transmission for performance knows/feels engine braking is 100% a thing. Drop the gear to the lowest you can without red-lining (80mph?, drop to 3rd), then 100% brakes. A lot of momentum/energy is absorbed from pushing all the components of the transmission, flywheel and engine at a disadvantageous gearing. Similarly, if you were to put it in neutral and try 100% braking it’d take much longer to stop. That difference is the engine breaking.
