A coin is used to simulate the probability of parents having
boy and
girl if they have a total of two children. A head represents having a girl, and a tail represents having a boy. The coin is flipped twice for each trial. The first flip represents the first child, and the second flip represents the second child. The experiment was performed
times, and the results are recorded in the following table.

Trial First Flip Second Flip
1 H H
2 H T
3 T H
4 H T
5 T T
6 H H
7 T H
8 H T
9 H H
10 T T
11 T T
12 H H

Based on the simulation, what is the probability that parents will have
boy and
girl if they have a total of two children?
