So let's say that u is 0 and f is 1. And now the notion of taking a probability-weighted sum makes some sense. So the mean of this distribution is going to be 0.4. That's this probability right here. Times 0 plus 0.6 times 1, which is going to be equal to this is just going to be 0. 0.6 times 1 is 0.6. So clearly, no individual can take on the value of 0.6.
