P(A)=1/2, P(B)=3/5, P(A∩B)=1/5. What is P(A∪B)?
P(A)=1/2, P(B)=3/5, P(A∩B)=1/5 है। P(A∪B) क्या है?
Show answer and explanation
Correct Answer
B. 9 / 10
ExplanationStep 1: Identify the concept: addition theorem. Step 2: P(A∪B)=P(A)+P(B)-P(A∩B). Calculation gives 9/10. Step 3: Exam tip: For a union, subtract the common part once.
Step 1: अवधारणा addition theorem है। Step 2: P(A∪B)=P(A)+P(B)-P(A∩B)। Calculation से 9/10। Step 3: याद रखें: Union में common part एक बार subtract करें।
