*If a quantum system of Hilbert space dimension mn is in a random pure*

state, the average entropy of a subsystem of dimension m ≤ n is

conjectured and evaluated in large m, n limit. It is shown that

there is less than one-half unit of information, on average, in the smaller

subsystem of a total system in a random pure state.
