If P(A)=0.4 P(B)=0.7 and A and B are independent then what is P(A ∩ B)?
यदि P(A)=0.4 P(B)=0.7 और A तथा B independent हैं तो P(A ∩ B) कितना होगा?
Show answer and explanation
Correct Answer
B. 0.28 / 0.28
ExplanationStep 1: For independent events P(A ∩ B)=P(A)P(B). Step 2: 0.4×0.7=0.28 so option B is correct. Step 3: When you see independent use multiplication rule.
Step 1: Independent events के लिए P(A ∩ B)=P(A)P(B) होता है। Step 2: 0.4×0.7=0.28 इसलिए option B सही है। Step 3: Independent word दिखे तो multiplication rule लगाएं।
