If P(A)=0.6 and P(B)=0.5 and P(A ∩ B)=0.2 then what is P(A ∪ B)?
यदि P(A)=0.6 और P(B)=0.5 तथा P(A ∩ B)=0.2 है तो P(A ∪ B) क्या होगा?
Show answer and explanation
Correct Answer
C. 0.9 / 0.9
ExplanationStep 1: P(A ∪ B)=P(A)+P(B)-P(A ∩ B). Step 2: 0.6 + 0.5 - 0.2 = 0.9. Step 3: Do not forget to subtract the common probability in union.
