यदि A और B कोई दो घटनाएँ हैं, तो P(A ∪ B) है
  1. AP(A) + P(B)P(A) + P(B)
  2. BP(A) + P(B) – P(A ∩ B)P(A) + P(B) – P(A ∩ B)
  3. CP(A) P(B)P(A) P(B)
  4. DMore than one of the aboveउपर्युक्त में से एक से अधिक
  5. ENone of the aboveउपर्युक्त में से कोई नहीं

Correct answer: (B) P(A) + P(B) – P(A ∩ B)P(A) + P(B) – P(A ∩ B)

Explanation

By the addition theorem, P(A ∪ B) = P(A) + P(B) - P(A ∩ B).योग प्रमेय से P(A ∪ B) = P(A) + P(B) − P(A ∩ B)।
