Final answer:
The note that indicates that the patient cannot have both conditions at the same time is option c. When two conditions are mutually exclusive, it means that they cannot occur together.
Step-by-step explanation:
The note that indicates that the patient cannot have both conditions at the same time is option c.
When two conditions are mutually exclusive, it means that they cannot occur together. In this case, the patient cannot have both conditions A and B simultaneously.
P(A AND B) = 0 indicates that the probability of having both conditions A and B at the same time is zero.
