Answer:

C. Children have much greater chance of having side effects than adults.

Step-by-step explanation:

It is known that the conditional probability for two events A and B is given by,

P(A|B)=\frac{P(A\cap B)}{P(B)}.

Then, according to the table, we have,

P(sideeffects|child)=\frac{P(sideeffects\cap child)}{P(child)}

i.e.  P(sideeffects|child)=\frac{20}{50}

i.e.  P(sideeffects|child)=0.40

Moreover,

P(sideeffects|adult)=\frac{P(sideeffects\cap adult)}{P(adult)}

i.e.  P(sideeffects|adult)=\frac{6}{50}

i.e.  P(sideeffects|adult)=0.12

As 0.40 > 0.12.

Children have more chances of having side effects than adults.

Hence, option C is correct.
