Answer:
Center: (0, 0)
Radius: 4
Step-by-step explanation:
Circle Standard Equation: (x - h)² + (y - k)² = r²
(h, k) is center
r is radius
We see that our <em>h</em> and our <em>k</em> are both 0.
∴ Our center is (0, 0), origin.
We see that our r² = 16
√r² = √16
∴ Our radius is equal to 4

The probability that at least one of them has been vaccinated is equal to 98.5% if 65% of the people have been vaccinated.
Considering P to be the probability that at least one is vaccinated and q to be the probability that none of the four are vaccinated; the sum of all the probabilities must equal 1; therefore,
P = 1 - q
As 65% of the population is vaccinated, therefore 35% are not vaccinated. Thus any person has a probability of 0.35 of not being vaccinated;
q = 0.35^4 = 0.015
P = 1 - 0.015
P = 0.985
Converting it into percentage;
P = 0.985 × 100 = 98.5%
Therefore the probability that at least one of them has been vaccinated is calculated to be 98.5%
