Question: P (D) = 0.4 P (B|D) = P (DB) = = 0.4 PB | D) = P (B|D) = PDB) = = P (DB)

P (D) = 0.4 P (B|D) = P (DB) = = 0.4

P (D) = 0.4 P (B|D) = P (DB) = = 0.4 PB | D) = P (B|D) = PDB) = = P (DB) = P(D) = P (DB) = PBD) = 0.65 What is the probability that a randomly chosen student received a grade of "B" or higher in the course?
