Putting four 1.1 ohm resisters in series creates a total resistance of 4 x 1.1 = 4.4 ohms. If these are the only elements in the circuit then current flow = V/R = 9v/4.4 ohms. But you mentioned bulbs - what bulbs? Do you mean that the 1.1 ohm resistors are actually bulbs?

There must be a diagram to go with the question - if you can figure out how to post it that would be helpful. Does the circuit consist of 4 resistors and 3 bulbs all in series with the battery? If so, do you know anything about the resistance of each bulb?
