If A and B are mutually exclusive and P(A)=0.3 P(B)=0.4 then what is P(A ∪ B)?
यदि A और B mutually exclusive हैं और P(A)=0.3 P(B)=0.4 है तो P(A ∪ B) क्या होगा?
Show answer and explanation
Correct Answer
C. 0.7 / 0.7
ExplanationStep 1: In mutually exclusive events the common part is zero. Step 2: Therefore P(A ∪ B)=0.3+0.4=0.7. Step 3: When events are mutually exclusive add probabilities directly.
Step 1: Mutually exclusive events में common part zero होता है। Step 2: इसलिए P(A ∪ B)=0.3+0.4=0.7। Step 3: Mutually exclusive दिखे तो probabilities सीधे add करें।
