comment Find the solutions to ${ 450 }^{ { (\sin x) }^{ 3 } }+{ 273 }^{ { (\cos x) }^{ 5 } }=2$
Number of solution is 8, as can be seen from this plot.

Every number is this equation is weird.

comment Conditional Distributions and Probabilities
$Y$ is a continuous random variable. Isn't it true that $Pr(Y=y|\eta)=0$?

comment Let $X$ and $Y$ be two Poisson random variables with same lambda parameter. What is the distribution of $\frac{X}{X+Y}$?
I am not sure what this distribution is, but it's definitely not uniform on $[0, 1]$.

This doesn't convince me.
