Final answer:
The probability that a randomly selected 3-year-old is enrolled in daycare is 40.8%, which can be expressed as a probability of 0.408.
Step-by-step explanation:
The probability that a randomly selected 3-year-old is enrolled in daycare, according to a certain country's department of education, is 40.8%. This percentage is the same as the probability, which can be expressed as a decimal, 0.408. Therefore, if you randomly select a 3-year-old child from this country, there is a 40.8% chance, or a probability of 0.408, that the child is enrolled in daycare. This is calculated simply by converting the percentage into decimal form, which is done by dividing the percentage by 100.
