If events A and B are independent and P(A)=1/2 and P(B)=2/5 then what is P(A ∩ B)?
यदि दो घटनाएं A और B स्वतंत्र हैं तथा P(A)=1/2 और P(B)=2/5 है तो P(A ∩ B) क्या होगा?
Show answer and explanation
Correct Answer
A. 1/5 / 1/5
ExplanationStep 1: For independent events P(A ∩ B)=P(A)P(B). Step 2: 1/2 × 2/5 = 1/5. Step 3: When you see independent remember the multiplication rule.
Step 1: independent events के लिए P(A ∩ B)=P(A)P(B)। Step 2: 1/2 × 2/5 = 1/5। Step 3: independent शब्द दिखे तो multiplication rule याद करें।
