If a disease has a 5% chance of being misdiagnosed, what is the probability of a correct diagnosis? (2019)
Step 1: Understand that the disease has a 5% chance of being misdiagnosed.
Step 2: Convert the percentage of misdiagnosis into a decimal. 5% is the same as 0.05.
Step 3: To find the probability of a correct diagnosis, subtract the probability of misdiagnosis from 1. This is because the total probability must equal 1 (100%).
Step 4: Perform the calculation: 1 - 0.05 = 0.95.
Step 5: The result, 0.95, represents the probability of a correct diagnosis.
