At The hillock of a postsynaptic neuron

At the hillock of a postsynaptic neuron, 4 EPSPs$$(13\mathrm{mV},12\mathrm{mV},5\mathrm{mV},7\mathrm{mV})$$and 3 IPSPs$$(-5\mathrm{mV},-6\mathrm{mV},-4\mathrm{mV})$$summate, what is the resultant potential at the trigger zone? Will the postsynaptic neuron produce an AP? Assume the neuron was at rest prior to stimulation.
