ollegr [7]

Answer:0.92

Step-by-step explanation:

Given

$57\%$ of Population is vaccinated

So, Probability of a person being vaccinated is $P=0.57$

and simultaneously , probability of not vaccinated is $1-P$

$=1-0.57=0.43$

Now, Probability that atleast one of them has been vaccinated is given by

$=1-P(\text{None of them is vaccinated})$

$=1-0.43\times 0.43\times 0.43$

$=1-0.0795$

$=0.92$
