The National - "Heavenfaced"

Song from  one of the trailers of the "The Theory of Everything"

Breathing Through The Nose

I found out that I have been breathing through the mouth which seems to be the case for quite a few people. From quite a few articles I have read, there could be dangers from breathing through the mouth so today I have been trying to  breathe more  through the nose.

While exercising, it seems difficult at first but I heard  it does improve later.



Here are some of the articles I  have read

Updated:
Here is an article which states otherwise about breathing  while running.

Conditional Probability


I have always found probability to be a tricky subject.. A tree diagram helps in dealing with more than one event but in  a single event, things can be different as  can be seen in one of the solutions from Khan Academy, World of Maths below:-
 Let A be the event that the first die is 1 and B be the event that the dice sum to 3We can find P(B | A) by finding all of the outcomes where the sum of the dice is 3, given that the first die is 1. There is only outcome that meets these conditions, and there are 6 total outcomes where the first die is 1,
Therefore, P(B | A)=16.

The video below appears to be dealing with more than one event.
