assalamualaikum dan salam sejahtera..

today my entry is about PROBABILITY..do u know what is it? alaaaa yg dok lam hutan bunyi krohhh..krohhhh..tu..yg haram dimakan tu...

dah2 jangan dilayan pening aku nie..PROBABILITY ni yg dalam add math tu..aku dah amek masa spm now time degree ni pon aku kena amek lagi..hellooooo..aku pakar okeyh benda nie..pakar sangat..x payah lah nak ulang benda yang sama.."tangan di dada mata ke atas"

Basic Probability Formulas

Probability Range

0 ≤ P(A) ≤ 1

Rule of Complementary Events

P(A^C) + P(A) = 1

Rule of Addition

P(A∪B) = P(A) + P(B) - P(A∩B)

Disjoint Events

Events A and B are disjoint iff

P(A∩B) = 0

Conditional Probability

P(A | B) = P(A∩B) / P(B)

Bayes Formula

P(A | B) = P(B | A) · P(A) / P(B)

Independent Events

Events A and B are independent iff

P(A∩B) = P(A) · P(B)

Cumulative Distribution Function

F_X(x) = P(X ≤ x)

Probability Mass Function

Probability Density Function

$fX(x) = dFX(x)/dx$

Covariance

$Cox(X,Y) = E(X-ux)(Y-uy) = E(XY) - ux*uy$

Correlation

$corr(X,Y) = Cov(X,Y)/(Std(X)*Std(Y))$

haaaaaaa....tengok!!!!!!!! betapa bnyak formula dia kan...

aku giler superb ni..giler lah....

sampai sekarang macam nak giler kerana benda nie..

AKU TAK FAHAM APE-APE PON DARI ZAMAN SPM SAMPAILAH KE DEGREE NI..PLEASEEEEE..SOMEBODY HELP ME..BENDA NI MACAM KO LETAK TALI GANTUNG KE LEHER KO THEN KO TAK MATI-MATI...SEKSA RASANYA! X PUN MACAM KO AMBIL PISAU THEN KAU KELAR2 JARI-JARI KAU TAPI X BERDARAH..KO JUST RASA SAKIT JE..HAAAA MACAM TU LA EDEN RASO JANG OOOOOOOOO....

mcam ni pon ye jugak rsanya..badan besor tapi x leh angkat..mcam situasi aku nie..dah amek degree tapi soalan probability yg spm aku still xleh nak jwb..okeyh fhm perumpamaan aku???

x fhm?????? diam je lah~

the end of my probability story...daaaaaaaaaa

PROBABILITY???HAA WHAT?
