In how many ways can 3 men and 2 women be arranged in a line if the men must be together?

Correct Answer: 36

Step 1: Treat the 3 men as one single unit. This means we consider them as 'MMM'.
Step 2: Now, we have 3 units to arrange: 'MMM', 'W', and 'W'.
Step 3: Calculate the number of ways to arrange these 3 units. This is done using the factorial of the number of units, which is 3! (3 factorial).
Step 4: Calculate 3! = 3 × 2 × 1 = 6. So, there are 6 ways to arrange the units.
Step 5: Next, we need to arrange the 3 men within their unit 'MMM'. There are 3 men, so we calculate 3! for them as well.
Step 6: Calculate 3! = 3 × 2 × 1 = 6. So, there are 6 ways to arrange the men within their unit.
Step 7: Finally, multiply the number of arrangements of the units by the arrangements of the men: 6 (units) × 6 (men) = 36.
