Checking Current in RL Circuit at t=0 - Typo Found?

[marstery]

I have an example where a 5v dc source is connected to a 10mh inductor then to 1k and 2k resistors in parallel.

In finding the current through the inductor at t=0:

written is:
IL(0) = 5v / (2/3k) = 7.5 ma

what i got was:
IL(0) = 5v / (3/2k) = 3.3 ma

I'm just checking to make sure i haven't lost mind or missed something.

The parallel combination of a 1k and 2k resistor is 1/(1+0.5) = 2/3. I think you just forgot the extra 1/ part?

right.
