This question already has an answer here:
Let us say Alice wants to communicate state |T> (also a qubit) to Bob. Given, they have an EPR Pair shared amongst them. Alice interacts her qubit with |T> and then sends the measured state (classical information) of qubits to Bob. Depending upon the measured state of qubits(00,01,10,11) Bob uses the quantum gates to get back |T>. But instead of doing that Bob could have decided upon using a particular quantum gate. So, he could have got the right information with a probability of 0.25 but at least he could have achieved faster than light teleportation with a probability of 0.25.
