Probability that at least one of them has been vaccinated is 96.07%
I am working on this problem backwards.
100% - 66% = 34% people are not vaccinated.
Selecting one person from the population, the odds they are not vaccinated is 34%. So, selecting three people, the probability that none of them are vaccinated is 0.34 X 0.34 X 0.34 = 0.03930.
Now subtracting from 1 and then converting it to percent:
1 - 0.03930 = 0.9607
0.9607 x 100% = 96.07%
96.70% is the probability that at least one of them has been vaccinated.
