the answer to your specific question is ...we don't know.

if you want the expected number of people that suffer undesirable side effects then use the formula $n\times p$

like  this 


x/121 = 1/11
--
x = 121(1/11)
---
x = 11 (# that will encounter unwanted side effects)

sure...or just 

$$121\times\frac{1}{11}=11$$
