Question

A boat is to be manned by eight men, of whom 2 can only row on bow side and 1 can only row on stroke side; in how many ways can the crew be arranged?

Answer 1

There are 10 ways the crew can be arranged on the boat.

Step-by-step explanation:

To determine the number of ways the crew can be arranged, we need to consider the different positions for each member of the crew. There are:

• 2 men who can only row on the bow side
• 1 man who can only row on the stroke side
• 5 men who can row on either side

For the 2 men who can only row on the bow side, there are 2 possible positions in the boat. For the 1 man who can only row on the stroke side, there is 1 possible position. For the remaining 5 men, there are 5 possible positions.

Therefore, the total number of ways the crew can be arranged is 2 * 1 * 5 = 10.
