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.

= 2/3 t
so option B and E are correct answer
Answer:
y=2/3x+5
Step-by-step explanation:
The change in y is 2
The change in x is 3
So, the rate of change, or slope is 2/3.
Since x=0 means y=5, then our linear function would be y=2/3x+5
