According to a certain country's department of education, 39.4% of 3-year-olds are enrolled in day care. What is the probabi

SCORPION-xisa [38]

Answer:

0.394

Step-by-step explanation:

Given:

Percent of 3 year-olds enrolled in daycare = 39.4%

The above statement means that if the total number of 3 year-olds is 100, then out of the 100 persons aged 3 years, the number of persons enrolled in a daycare is 39.4.

Now, probability of an event is the ratio of the favourable outcomes for that event to the total number of outcomes.

Here, the favourable number of outcomes is the number of persons aged 3 years enrolled in a daycare which is equal to 39.4.

The total number of outcomes is the total number of 3 year-olds which is 100.

Therefore, the probability that a randomly selected 3-year-old is enrolled in daycare is given as:

$P(enrolled)=\frac{39.4}{100}=0.394$

(x + 6)(x + 5) = 72

x² + 11x + 30 = 72
