Hi cooljackiec;
The area above the triangle that the line y = x makes is twice as large as the area below the triangle. y is a 2 to 1 favorite. There is only one probability that is twice its complement. That is 2 / 3. The probability the P(y > x ) = 2 / 3 so P(x < y ) = 2 / 3.

Hi cooljackiec
Bobbym's answer is correct. Take a closer look and try plotting a few values fir (x,y) to see which area the points will belong.
And, welcome to the forum!

actually, bobbym
The point (x,y) satisfies x<y if and only if it belongs to the shaded triangle bounded by the lines x=y,y=2 , and , x=0 the area of which is 2. The rectangle has area 6, so the probability in question is 1/3

Math will wait.

Let the problems of the day be sufficient for the day.

Yawning, sleepy eyelids, a general buildup of toxins and a lowering of body temperature all signalling the need for sleep...

Hi bobbym
yes that's how i did it,i just flipped the rectangle around the y=x line.

Hi;
Or the answer is the area enclosed by the rectangle on top and the line y = x.

Hi bobbym
i think i switched x and y coordinates.
