Question 1174104
.
In a large population, 62% of the people have been vaccinated. If 4 people are randomly selected, 
what is the probability that at least one of them has been vaccinated?
Give your answer as a decimal to 4 places.
~~~~~~~~~~~~~



<pre>
This probability is the COMPLEMENT to the probability of the event "No one of 4 has been vaccinated",


and THEREFORE is equal to  1 - {{{(1-0.62)^4}}} = {{{1 - 0.38^4}}} = 0.9791.
