1.  How do you find the total resistance of 3 identical resistors of R ohms each when they are connected in series?

2.  How do you find the total resistance of 3 identical resistors of R ohms each when they are connected in parallel?

Please share the formula you're using in each case.

In order to answer, I believe we are to disregard the fact that the resistance of the bulbs filament is dependent to a great degree on the temperature (cold being a lower resistance. However, if you assume the internal resistance remains the same for each bulb in both configurations you can answer this with Ohms Law.
