The estimated probability that only 1 of 3 randomly selected students rides in a car to school is 0.6.
Given
A survey finds that 40% of students ride in a car to school.
Eri would like to estimate the probability that if 3 students were randomly selected, only 1 ride in a car.
<h3>Probability</h3>
Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event.
The total number of trials is 20, and a number of 1 student trial = 12.
The estimated probability that only 1 of 3 randomly selected students rides in a car to school is;
Hence, the estimated probability that only 1 of 3 randomly selected students rides in a car to school is 0.6.

- 2.6
- Add 9.3025 and 2.6 = 11.9025
- Divide 3.70135110 by 11.9025
= 0.31097257
Answer:
D. We can label the rational numbers with strings from the set (1, 2, 3, 4, 5, 6, 7, 8, 9, / -) by writing down the string that represents that rational number in its simplest form. As the labels are unique, it follows that the set of rational numbers is countable.
Step-by-step explanation:
The label numbers are rational if they are integers. The whole number subset is rational which is written by the string. The sets of numbers are represented in its simplest forms. The rational numbers then forms numbers sets which are countable.
