Is the expected value of wiener processes multiplied zero?

94 Views Asked by At

So, I have a standard Wiener process, and $l_3>l_2>l_1>0$, and I would like to calculate $\mathbb{E}(W_{l_1}W_{l_2}W_{l_3})$.

I got that it's zero, is the solution good? I have a solution for it, but I’d be wondering how else it does?!
