im trying to wire an LED into my project to Finnish it off for my GF's B-day heres the parts i have
Resistors are all ¼-watt resistors with 5% tolerance.
10 each of 10, 1k, 10k, and 100k
8 each of 47, 100, 470, 2.2k, 4.7k, and 1Meg
4 each of 150, 15k, and 220k
i also have a AAA Battery Pack to power my LED
the LED is 20mA 3.2V (Typical), 3.8V (Max)
my Question is with the parts i have how do i wire the LED
Second Question:
do i wire the LED to the positive or Negative terminals I haven't done wiring in so long i forgot most of it but if i can know which resistors and where to put them i can Finnish this in time.
Thanks You!

Three cells connect in series to make 4.5V
65 ohm resistance is required from calculation,but use one 47 ohm plus one 10 ohm connect in series to make 57 ohm is good enough.
Connection : +4.5V --- 47 ohm --- 10 ohm --- anode of LED ---- cathode of LED --- negative of 4.5V
