Solution:
Given, probability of recovering = 0.75
Number of patients = 48
1. Expected Value:
The expected value of the number of recoveries can be calculated as follows:
Expected Value = Number of patients × Probability of recovering
Expected Value = 48 × 0.75
Expected Value = 36
2. Variance:
The variance of the number of recoveries can be calculated as follows:
Variance = Number of patients × Probability of success × Probability of failure
Variance = 48 × 0.75 × 0.25
Variance = 9
3. Standard Deviation:
The standard deviation can be calculated by taking the square root of the variance:
Standard Deviation = √(Variance)
Standard Deviation = √(9)
Standard Deviation = 3
Therefore, the correct answer is option 'D' (3).
