That is correct!
okay,thank you!
You're welcome.
To find the probability of the middle child being a boy, we need to count the number of outcomes where the middle child is a boy and divide it by the total number of outcomes.
Looking at the sample space, we have 8 possible outcomes. Out of these, there are 3 outcomes where the middle child is a boy: BBB, GBB, and GBG.
Therefore, the probability (in simplest form) that the middle child is a boy is 3/8.
