For two mutually exclusive events A and B what is P(A union B)?

A. P(A)+P(B)

Step 1: Identify the concept: this is mutually exclusive events. Step 2: Mutually exclusive events cannot occur together so union probability is P(A)+P(B). Step 3: Remember no overlap means add probabilities.

Step 1: concept पहचानें: यह mutually exclusive events है। Step 2: Mutually exclusive events साथ में नहीं हो सकते इसलिए union probability P(A)+P(B) होती है। Step 3: No overlap means add probabilities याद रखें।
