This is true. I read somewhere like 60% of all graduate students in the US are foreigners. Meanwhile admissions into grad programs for citizens are higher than ever.

>If I select two integers at random between 1 and 100, what is the probability that their sum will be prime?

Introduce two vectors A and B.
A is the vector whose entries is 1 if index = prime, else 0.
B is the vector whose entry with index = c contains the number of combinations (x,y) such that the additive function f(x,y) = x+y equals c.

$A = (0,0,1,1,0,1,0...), B = (0,0,1,2,3,4,5, ... 5,4,3,2,1)$

Multiplying A and B results in the total number of possible combinations (x,y) leading to a prime number. If you want to compare this to the total number of possible correlations, introduce a new vector C = $(1,1,1,1,1,1,1,1)$

$A * B / C * B = A/C$ . A, here the number of primes between 1 and n, can be approximated by $n/log(n)$ .

Thus $A/C = (n/log(n))/n = 1/log(n)$ which is the desired result.

Because we're interested in calculating the probability of finding a prime for any number up to 200, we put in 1/log(200) = 0.1887 = 18.87 %.

Is it possible to select the same integer twice?
If so, you have to consider 5050 cases instead of 4950. Shouldn't really matter disregarding the additional 100 additional cases, only 1+1 of which is prime, but we're aiming for mathematical precision here.

Can the 9/11 conspiracytards explain why they would even bother demolishing World Trade Center 7? By the time it went down it was completely evacuated so it wasn't even that big of a deal. If it was a controlled demolition all it did was spread nonstop doubt on the official version of events for the next 2 decades. It makes no sense.

Breathing isn’t a crime, being oppressive via the current capitalist system isn’t a crime. Sorry not sorry white people play the current game better then the browns (white people includes Jews).

Are there a good alternative to taking a nap?

The issue is that I take 3 naps of 90 minutes during the day, at least since some weeks ago.

So when I'm ready to not sleep is 4-5 PM already.

I need some way to allow my brain to rest but without taking a 90 minutes nap.

What if I took like 80mg fluoxetine daily? Would it make me really happy instead of just a little less depressed?

I'm supposed to go to 80mg cause i have OCD too but worried it will reduce the effectiveness for my depression if I do?
