Probability of min(x,y)<1 [closed]
$begingroup$
How can I solve this?
$f_{xy}(x,y)$ is a joint probability distribution defined by
$$f_{xy}(x,y)=ye^{-y(1+x)}$$ for $ x,y>0$.
And for other $x,y$ the joint probability distribution defiend by
$$f_{xy}(x,y)=0$$
And the Question is Find the probability of:
P(min(x,y)<1)=?
Please Write Your Full Answer.

Draw the region ${min(x,y) < 1}$ on the $x$-$y$ plane and integrate the density over that region.

$$P(min(x,y)<1)=1-P(min(x,y)geq 1) = 1-P(xgeq 1,ygeq 1)$$
$$ = 1-int_{1}^{infty} int_{1}^{infty} ye^{-y(x+1)}dxdy.$$
So we have that
$$P(min(x,y)<1) = 1-int_{1}^{infty}e^{-(y+1)}dy=1-frac{1}{e^2}.$$
