Bayoumi's assistance was un-tasked hospitality (competing explanation)
The housing and banking help was coincidental community support by a gregarious expatriate, consistent with KSM's instruction that the operatives seek mosque help, and does not imply Saudi-government tasking or plot knowledge.
Likelihood — more or less than 50%
48%
Equal to 50% — the sources do not tip either way
Start at 50%. Move by half of the net source score after uncertainty. Net source score is -0.05 (from −1 contradict to +1 support). Uncertainty is 12%. So 50% + 50% × -0.05 × 88% remaining certainty = 48%.
0.5 + 0.5 × -0.05 × (1 − 0.12) = 0.478
