Two boys and three girls are going to sit around a table with 5 different chairs. If the two boys want to sit next to Jill, in how many possible ways can they be seated?
Anchor Jill in any chair
The two boys can sit on either side of her in 2 ways
And the other two girls can be arranged in 2! = 2 ways
So 2 * 2 = 4 ways
