We've two variables =2 with p=1/3, =4 with p=1/3, x=5 with p=1/3 y=1 with p=1/4, y=3.5 with p=1/2, y=6 with p=1/4

1) compare them using first order stochastic dominance 2)compare them using second order stochastic dominance 3) without any calculation, establish if its possible to compare these variables when u(x)=ln(x)
