Question

question number 1. hospital records show that 16% of all patients are admitted for heart disease, 26% are admitted for cancer (oncology) treatment and 4% receive both coronary and oncology care. what is the probability that a randomly - selected patient is admitted for something other than coronary care? (note that heart disease is a coronary care issue.) 0.70 0.74 0.80 0.84 0.96 none of the above.

Explanation:

Step1: Identify relevant percentages

We know that 16% are admitted for heart - disease, 26% for cancer and 4% receive both coronary and oncology care.

Step2: Calculate the percentage of patients admitted for coronary or oncology care

Using the formula \(P(A\cup B)=P(A)+P(B)-P(A\cap B)\), where \(A\) is the set of patients with heart - disease (coronary care) and \(B\) is the set of patients with cancer (oncology care). So \(P(A\cup B)=16 + 26-4=38\%\).

Step3: Calculate the percentage of patients admitted for something other than coronary care

The total percentage of all patients is 100%. The percentage of patients admitted for coronary or oncology care is 38%. So the percentage of patients admitted for something other than coronary care is \(100 - 38=62\%\) or \(0.62\). Since this value is not in the given options, the answer is None of the above.

Answer:

None of the above.
