In The Brothers' War collector boosters (12 packs per box), you can expect about 0.060 serialized cards per box - roughly 0.0050 per pack. That works out to a 5.8% chance of pulling at least one serialized card per box, or about 1 in 17 for your first hit. The chase end is often Mox Amber (about 1 in 2450 for that specific printing).
Numbered /N printings that appear in a dedicated rare slot. Among the scarcest pulls in modern collector boosters.
Per-printing expected pulls and odds of at least one per box.
