Let me fix that math. Some of the inputs were a bit off.
There were actually only 4 POTUS tweets (not counting RTs) and only 24 Q posts since noon. It was a roughly 7 hour period when they were both active.
420/4=105
(1/105)*24=0.229
0.229^3=0.012, or 1.2%, or about 1-in-83 chance of three zero-deltas between 4 POTUS tweets and 24 Q posts within the 7 hour time period. Approximately.
