Q
Q: A patient is diagnosed with a bacterial infection and is prescribed antibiotics. If the bacteria have a resistance rate of 25%, what is the probability that a randomly selected bacterium is susceptible to the antibiotic?
Solution: If 25% of the bacteria are resistant, then 75% are susceptible to the antibiotic.
Steps: 5
Step 1: Understand that the resistance rate of the bacteria is 25%.
Step 2: Recognize that if 25% of the bacteria are resistant, the remaining bacteria are susceptible.
Step 3: Calculate the percentage of susceptible bacteria by subtracting the resistance rate from 100%.
Step 4: Perform the calculation: 100% - 25% = 75%.
Step 5: Conclude that 75% of the bacteria are susceptible to the antibiotic.
