統計例確率

従属事象AとBのP(A∩B)を求める

$P (A) = 0.6$ , $P (B) = 0.07$ , $P (B g i v e n A) = 0.05$

ステップ 1

$A$ と $B$ が従属事象のとき、 $A$ と $B$ が発生する確率は $P (A \cap B) = P (A) \cdot (P (B | A))$ です。これは従属事象 $A$ と $B$ の乗法法則と呼ばれます。

$P (A \cap B) = P (A) \cdot (P (B | A))$

ステップ 2

既知数を記入します。

$P (A \cap B) = 0.6 \cdot 0.05$

ステップ 3

$0.6$ に $0.05$ をかけます。

$P (A \cap B) = 0.03$
