Compare the probability that an adult has side effects with the probability
that a child has side effects. Draw a conclusion based on your results.
A. P(side effects child) = 0.20
P(side effects adult) = 0.60
Conclusion: Children have a much greater chance of having side
effects than adults.
B. P(side effects child) = 0.40
P(side effects adult) = 0.12
Conclusion: Children have a much greater chance of having side
effects than adults.
C. P(side effects child) = 0.20
P(side effects adult) = 0.60
Conclusion: Children have a much lower chance of having side
effects than adults.
D. P(side effects child) = 0.40
P(side effects adult) = 0.12
