SUMMARY

The discussion focuses on solving a bivariate probability problem involving the joint probability density function f(x,y) = 6(1-y) for the region defined by 0 <= x <= y <= 1. The objective is to find P(x <= 3/4, y >= 1/2) by analyzing the non-zero area of the function and setting up a double integral. Participants emphasize the importance of visualizing the regions in the xy-plane to correctly establish the limits for integration.

PREREQUISITES
  • Understanding of joint probability density functions
  • Knowledge of double integrals in calculus
  • Familiarity with the concept of probability regions in the xy-plane

Homework Statement


Let x and y have the join probability density function given by

f(x,y) = 6 (1-y) 0<= x<=y<= 1
= 0 elsewhere
Find P(x<=3/4, y=> 1/2)


Homework Equations





The Attempt at a Solution



I know you have to find the probability in 2 parts.. but i am unsure how to do it?? any advice will be appreciated, thanks in advice.

start by drawing the following in the x y plane
- the area where f(x,y) is non-zero
- the region x<= 3/4
- the region y >= 1/2

the use this information to set up a double integral of f(x,y) over the required region
