A sample set contains every possible outcome.
The answer would be:
(R, 1), (R, 2), (R, 3), (R, 4), (R, 5), (R, 6), (B, 1), (B, 2), (B, 3), (B, 4), (B, 5), (B, 6)}
Let n be the required number of 33 ohm resistors.


The required number of 33 ohm resistors in parallel is 6 resistors.
1: positive
2: negative
3: positive
4: negative
