For the Erdős–Rényi random graph G n, p, we give a precise asymptotic formula for the size α ˆ t (G n, p) of a largest vertex subset in G n, p that induces a subgraph with average degree at most t, provided that p= p (n) is not too small and t= t (n) is not too large. In the case of fixed t and p, we find that this value is asymptotically almost surely concentrated on at most two explicitly given points. This generalises a result on the independence number of random graphs. For both the upper and lower bounds, we rely on large deviations inequalities for the binomial distribution.
