Penjelasan:
# "Prasyarat:" P (AuuB) = P (A) + P (B) -P (AnnB) …. (bintang) #.
#P (AuuBuuC) = P (AuuD), "di mana," D = BuuC #, # = P (A) + P (D) -P (AnnD) ………. kerana, (bintang) #, # = P (A) + warna (merah) (P (BuuC)) - warna (biru) (P Ann (BuuC)) #, (P (B) + P (C) -P (BnnC)) - warna (biru) (P (AnnB) uu (AnnC)
(=) (P) (P), # = P (A) + P (B) + P (C) -P (AnnB) -P (BnnC) -P (AnnC) + P (AnnBnnC), #
