Question (select most suitable option)

  If f(x, y) is bivariate probability density function of continuous random variables X and Y then marginal density function of Y i.e. h(y) is:
\(\int\limits_{-\infty}^\infty f(x,y)\,dx\)
\(\int\limits_{-\infty}^\infty f(x,y)\,dy\)
\(\int\limits_{-\infty}^\infty \int\limits_{-\infty}^\infty f(x,y) \,dx \,dy\)
\(\int\limits_a^b \int\limits_c^d f(x,y) \,dy \,dx\)
