Question ، p(A)=0,3 حادشتان حيث B , A 11p(AB)=0,2p(AB)=0,7p(B)\begin{array}{l} \text { ، } \quad p(A)=0,3 \text { حادشتان حيث B , A } 11 \\ p(A \cap B)=0,2 \cdot p(A \cup B)=0,7 \\ p(B) \end{array}

Studdy Solution
حل المعادلة لإيجاد p(B) p(B) :
0.7=0.1+p(B) 0.7 = 0.1 + p(B)
p(B)=0.70.1 p(B) = 0.7 - 0.1
p(B)=0.6 p(B) = 0.6
الاحتمال المطلوب هو:
0.6 \boxed{0.6}
