And the sentences are P or not P, P and not P,

And then this term over here, this whole thing over here, is going to be plus p times 1 is p. p times negative 2p is negative 2p squared.

Let's say that this is our grammar

And if you want to factor a p out of this, this is going to be equal to p times, if you take p divided p you get a 1, p square divided by p is p.

Once again, based on this P, I'm going to start bringing in rules 1 and 2.

Now in probability terms, people often write it as follows

F, L, E, P, T, P L, E, P, F, L, F, L, E, P, T, P, L, F, E, T.

Let me just do this over here.

So chart state 0 includes the following parse states

So that cancels out.

So this is going to be equal to 1 minus p.

Another way to think about that is let's say that we're in a particular state like this one

P of A given B where B is the evidence and A is the variable we care about is P of B given A times P of A over P of B.

P of X3 given X1 is the sum of P of X3 given X1 and A times P of A given X1 plus the A complement, which is X3, conditional X1 and not A times P of not A given X1.

All right. E, F, L, E, P, T P, L, E, P, F, L, E L, E, P, T, L, P, E, F, E, T, Z, E, T...

It's that grammar of balanced parentheses.

You can actually compute this using total probability where P(Y) equals P(Y_BAR_X) times P(X) plus P(Y_BAR_ X) times (P X).

Valid.

P

p.

What's next?

P .

P ... P ...?

Teacup!

Similarly, over here I'm going to apply rule one three times.

So, to get all 3 of them together, we just multiply these by 3.

Now let's add that pink p to both sides of this equation.

And right here, this environment is called PyScripter.

P of happiness given S and R times P of S and R, which is of course the product of those 2 because they are independent, plus P of happiness given not S R, probability of not as R plus P of H given S and not R times the probability of P of S and not R plus the last case,

The first one looks pretty good. I just apply rule 1.

So p times 1 minus p, which is a pretty neat, clean formula.

In these other examples we were picking 30 percent, but now we can say it's p, it's the percentage off.

Here, you can watch our brave bulls battle with their horns.

So we're going to move these dots over here and get

The second thing we learned has to do with negation of probabilities.

Now divide both sides by 1 plus i.

So for example we can say

Armed with this number, the rest now becomes easy, which is we can use Bayes' rule to turn this around.

So, of the 8 possible outcomes of the coin flips, those 3 are the ones you want to count.

It takes 1 parameter to specify P of A from which we can derive P of not A.

So let's say that that's the nucleus and I'll just draw their p orbitals.
