Mutually exclusive events are events that cannot occur at the same time. we commonally call these events disjoint events also. AS per the definition given in the class 11 math probability chapter;

Two events A and B are said to be mutually exclusive if: P (A? B)=0

For Example:
When rolling a single die:

Let event A = getting 2 on top

Let event B = getting 3 on top

Since the number on the top cannot be 2 and 3 at the same time, So A and B are mutually exclusive events.

Students can check the CBSE Class 11 Chemistry text book for NCERT solutions for class 11 hydrocarbons with diagrams. Students must practice the diagram solutions to master the questions.
