In a line of three boys and two girls, what is the likelihood that each girl has at least one more boy in front of her than the number of girls ahead of her?
- 1/2
- 1/3
- 2/3
- 3/4
Correct answer: 1/2
Solution
The condition that each girl has more boys than girls ahead of her is satisfied in exactly half of the total arrangements. This is due to symmetry in the possible orderings of boys and girls.
