Probability of an adult who needs correction = 82% or 0.82
So, probability of an adult who does not needs correction = 1 - 0.82 = 0.18
If 12 adults are randomly selected, the probability that at least 11 of them need correction for their eyesight is:
12C11
+ 12C12
= 12*0.11*0.18 + 1*0.09*1
= 0.238+0.09
= 0.328 or 0.33
And, yes, 11 is significantly a high number of adults requiring eyesight correction.
