Question 1174102
<pre><font face = "Tohoma" size = 3 color = "indigo"><b>
 Hi,

In a large population, 64% of the people have been vaccinated.
If <u>4 people</u> are randomly selected:              
 
what is the probability that at least one of them has been vaccinated?

  
P( x≥ 1) = 1 - binomcdf(4, .64, 0)  = 1 - .0168 = .983 (decimal to 3 places)
            
Wish You the Best in your Studies.
 Solution works Great... with proper entering.
