#problem()
|
|
Charlie has two children. \
|
|
One of them is a boy born on a Tuesday. \
|
|
What is the probability that Charlie has two boys?
|
|
|
|
#solution([
|
|
$13 / 27$, which notably isn't $1/2$.
|
|
|
|
#v(2mm)
|
|
|
|
Draw a $14 times 14$ square, highlight the possible cases, and you'll see it. \
|
|
|
|
#v(2mm)
|
|
|
|
Order is very important in this problem. \
|
|
If we knew that the _first_ child was a boy born on Tuesday,
|
|
the probability of two boys would be $1/2$. \
|
|
Also consider a smaller case where a week has two days.
