Question

Assertion: There are three doors to a room The number of ways in which a student can enter the room and leave it by a different door is 6.
Reason: If an operation can be performed in m ways and another operation can be perfO rmed in n ways thenthe two operations in succession can be performed in mn ways.

  1. A is true, R is true and R is the correct explanation for A    
  2. A is true, R is false and R is the not the correct explanation for A    
  3. A is true, R is false    
  4. A is false, R is true.    

The correct answer is: A is true, R is true and R is the correct explanation for A


    A equals 3 cross times 2 equals 6
