The following questions refer to the above diagram of a voltaic cell. See Attachment:
a. Write the balanced net ionic equation for the thermodynamically favored redox reaction that occurs in the galvanic cell above.
b. Calculate the standard cell potential, E^o, in volts for the thermodynamically favored reaction that occurs in this cell.
c. What concentrations of Ag^+ and Pb^2+ are necessary for the cell to produce the standard cell potential calculated in part b.
d. What electrode is the anode and which is the cathode in the above cell.
f. In which direction are the electrons flowing?

lead has less reduction potential than silver ...so Ag+  reduces and  Pb oxidizes in the given galvanic cell.
Ag is the cathode(reduction) and Pb is the anode (oxidation)...
workout Eocell = E0cathode +E0anode
Electrons are flowing from oxidation half cell to reduction half cell ....anode (Pb) to cathode  (Ag)
Check the definition of standard reduction potential..concentrations are specified ...It is for 1Molar at 25 degree C
