    "abstract": "Following the recent work of Caves, Fuchs, and Rungta [Found. of Phys. Lett.\n{\\bf 14} (2001) 199], we discuss some entanglement properties of two-rebits\nsystems. We pay particular attention to the relationship between entanglement\nand purity. In particular, we determine (i) the probability densities for\nfinding pure and mixed states with a given amount of entanglement, and (ii) the\nmean entanglement of two-rebits states as a function of the participation\nratio.",
