+#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.
