Statistika Contoh

P (A) = 0.006

$P (A) = 0.006$ ,

P (B) = 0.2

$P (B) = 0.2$ ,

P (B g i v e n A) = 0.3

$P (B g i v e n A) = 0.3$

Langkah 1

Menggunakan kaidah Bayes,

P (A | B) = \frac{P (B | A) P (A)}{P (B)}

$P (A | B) = \frac{P (B | A) P (A)}{P (B)}$ .

P (A | B) = \frac{P (B | A) P (A)}{P (B)}

$P (A | B) = \frac{P (B | A) P (A)}{P (B)}$

Langkah 2

Substitusikan nilai-nilai yang diberikan

P (A) = 0.006

$P (A) = 0.006$ ,

P (B) = 0.2

$P (B) = 0.2$ , dan

P (B | A) = 0.3

$P (B | A) = 0.3$ ke dalam kaidah Bayes.

P (A | B) = \frac{(0.3) \cdot (0.006)}{0.2}

$P (A | B) = \frac{(0.3) \cdot (0.006)}{0.2}$

Langkah 3

Sederhanakan

P (A | B) = \frac{(0.3) \cdot (0.006)}{0.2}

$P (A | B) = \frac{(0.3) \cdot (0.006)}{0.2}$ .

Langkah 3.1

Kalikan

0.3

$0.3$ dengan

0.006

$0.006$ .

P (A | B) = \frac{0.0018}{0.2}

$P (A | B) = \frac{0.0018}{0.2}$

Langkah 3.2

Bagilah

0.0018

$0.0018$ dengan

0.2

$0.2$ .

P (A | B) = 0.009

$P (A | B) = 0.009$

P (A | B) = 0.009

$P (A | B) = 0.009$
