A + 1 = 1 A in parallel with
closed = “CLOSED” universal parallel circuit Annulment
A + 0 = A A in parallel with
open = “A” universal parallel Identity
A . 1 = A A in series with
closed = “A” universal series circuit Identity
A . 0 = 0 A in series with
open = “OPEN” universal series Annulment
A + A = A A in parallel with
A = “A” idempotent parallel circuit Idempotent
A . A = A A in series with
A = “A” idempotent series circuit Idempotent
NOT A = A NOT NOT A
(double negative) = “A” Double Negation
A + A = 1 A in parallel with
NOT A = “CLOSED” complement parallel circuit Complement
A . A = 0 A in series with
NOT A = “OPEN” complement series circuit Complement
A+B = B+A A in parallel with B =
B in parallel with A absorption parallel circuit Commutative
A.B = B.A A in series with B =
B in series with A absorption series circuit Commutative
A+B = A.B invert and replace OR with AND de Morgan’s Theorem
And for those who took part in the NME
No
Not the New Musical Express
It was the
National Mathematical Experiment

Those people proved that
1+1 =3
Especially when working out averages etc

A.B = A+B invert and replace AND with OR de Morgan’s Theorem

Binomial Probability Formula

A probability formula for Bernoulli trials. The probability of achieving exactly k successes in n trials is shown below.

Formula:

n = number of trials
k = number of successes
n – k = number of failures
p = probability of success in one trial
q = 1 – p = probability of failure in one trial

Example:
You are taking a 10 question multiple choice test. If each question has four choices and you guess on each question, what is the probability of getting exactly 7 questions correct?

n = 10
k = 7
n – k = 3
p = 0.25 = probability of guessing the correct answer on a question
q = 0.75 = probability of guessing the wrong answer on a question

No panic here
Could have sworn BJ said
The higher number

No it’s not the number of shares in Lloyds
It’s the number of brew cases of Omicron virus

Time to buy more shares ?

Got that a bit wrong
For now
Only £4000 so no sweat

Good price
We will see

Just watched a hypocrite , a liar and a thief (of public money), an adulterer. What a country we have allowed ourselves to become.
What channel is Tony on

Please could you post the list of guesses for the end of year competition
Don’t think I will win it this year
Thanks
