comment probability problem in a die game
There are six states of the form $3+1+0$, three states of the form $2+2+0$ and three states of the form $2+1+1$. All but the last three are absorbing states, so the diagram need not be big.

comment Confidence interval of median of log-normal distribution
Some thoughts: The question mentioning $101$ families, i.e. an odd number, might make it more likely that the median was intended. You seem to have assumed that Y is normally distributed rather than X being exponentially distributed. And if $Y=\ln(X)$ then $X$ must be positive

comment Probability of decision on arrival of “new” information
While your final conclusion is correct, I think your paragraph 2 and the next paragraph are confused between for example "Chris stays" and "teacher says Chris stays".

comment How do I solve a double integral with an absolute value?
The first range for $x$ covers the values for which $x \ge y$ and $x \in [0,1]$. The second range for $x$ covers the values for which $x \le y$ and $x \in [0,1]$.

comment How do I solve a double integral with an absolute value?
It separated the cases where $|x-y|=x-y$ from those where $|x-y|=y-x$, i.e. those where $x \ge y$ from those where $x \le y$ (since those where $x=y$ have measure $0$)
