Answer:
The probability is [tex]P(3) =0.255[/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 200
The number that were never vaccinated is k = 17
The number that were vaccinated once is m = 30
The number that were vaccinated twice is p = 58
The number that were vaccinated three times is q = 51
The number that were vaccinated four times r = 38
The number that were vaccinated five times s = 7
Generally the probability that a randomly chosen person out of this 200 is vaccinated 3 times is mathematically represented as
[tex]P(3) = \frac{q}{n}[/tex]
=> [tex]P(3) = \frac{51}{200}[/tex]
=> [tex]P(3) =0.255[/tex]
