Final answer:
The probability of capsule B having microbial contamination is 1.03%, while capsule D has a probability of 0.98% for microbial contamination, calculated by summing the individual probabilities of microbial contaminants.
Step-by-step explanation:
The student's question pertains to the probabilities of contamination in medicine capsules due to the presence of heavy metals and microbial contamination from various bacteria such as E. coli, Staphylococcus, Pseudomonas, and Salmonella. To determine the probability of capsule B having microbial contamination, we must add the probabilities of all microbial contaminants listed for capsule B. These are 0.22% for E. coli, 0.31% for Staphylococcus, 0.21% for Pseudomonas, and 0.29% for Salmonella, which sums up to a collective probability of 1.03%. The table does not provide sufficient data to directly compare the probability of capsule B having microbial contamination with that of capsule D. However, a similar calculation for capsule D reveals the collective probability of microbial contamination as 0.98%, based on the given individual probabilities for the various microorganisms.
