Step 1:

Identify the Recovery Rate: The recovery rate for the disease is given as 70%. This means that 70 out of every 100 patients are expected to recover.

Total Number of Patients: The total number of patients in the group is 20.

Explanation:-

To find how many patients are expected to recover, you multiply the total number of patients by the recovery rate. Convert the recovery rate to a decimal for this calculation:

Step 2:-

Calculate the Expected Number of Recoveries:

Recovery Rate (decimal)=70%=0.70

Perform the Calculation: Multiply the total number of patients by the decimal recovery rate:

Expected Recoveries=20×0.70

Explanation:- Patients are expected to recover, Expected Recoveries=14.Thus, based on the 70% recovery rate, 14 out of 20 patients are expected to recover.

Final Answer:-

Expected Recoveries=14

Thus, based on the 70% recovery rate, 14 out of 20 patients are expected to recover.
