The correct Answer is:
To solve the problem, we need to verify the two statements regarding the number of ways to divide and distribute six different objects. We will analyze each statement step by step. ### Step 1: Analyze Statement 1 **Statement 1**: The number of ways in which six different objects can be divided equally into 2 sets is 10. To find the number of ways to divide 6 different objects into 2 equal sets, we can use the formula: \[ \text{Number of ways} = \frac{n!}{k! \cdot k! \cdot m!} \] where: - \( n \) is the total number of objects (6 in this case), - \( k \) is the number of objects in each set (3 objects in each set since we are dividing into 2 sets), - \( m \) is the number of sets (2 in this case). Using the formula: \[ \text{Number of ways} = \frac{6!}{3! \cdot 3! \cdot 2!} \] Calculating the factorials: - \( 6! = 720 \) - \( 3! = 6 \) - \( 2! = 2 \) Now substituting these values into the formula: \[ \text{Number of ways} = \frac{720}{6 \cdot 6 \cdot 2} = \frac{720}{72} = 10 \] Thus, **Statement 1 is true**. ### Step 2: Analyze Statement 2 **Statement 2**: The number of ways in which six different objects can be distributed equally among two persons is 20. For distributing 6 different objects equally among 2 persons, we can use a different formula: \[ \text{Number of ways} = \frac{n!}{k! \cdot (n-k)!} \] where: - \( n \) is the total number of objects (6), - \( k \) is the number of objects each person receives (3). Using the formula: \[ \text{Number of ways} = \frac{6!}{3! \cdot 3!} \] Calculating: \[ \text{Number of ways} = \frac{720}{6 \cdot 6} = \frac{720}{36} = 20 \] Thus, **Statement 2 is also true**. ### Conclusion Both statements are true: - Statement 1 is true: The number of ways to divide 6 different objects into 2 sets is indeed 10. - Statement 2 is true: The number of ways to distribute 6 different objects equally among 2 persons is indeed 20. However, it is important to note that Statement 1 is not a correct explanation for Statement 2 because the context of division and distribution is different.
