Answer: The required probability is 0.439.
Step-by-step explanation:
Since we have given that
Percentage of 3- year old are enrolled in day care = 43.9%
So, the probability that a randomly selected 3 year old is enrolled in day care is given by
[tex]\dfrac{43.9}{100}\\\\=\dfrac{439}{100\times 10}\\\\=\dfrac{439}{1000}\\\\=0.439[/tex]
Hence, the required probability is 0.439.
