Answer 1

Given: A survey of 100 high school students provided this frequency table on how students get to school:

Required: Probability that a random selected student does not drive to school.

Step-by-step explanation:

Let E be the event that a random selected student does not drive to school.

`P(E)=\frac{Favourable\text{ Outcomes}}{Total\text{ outcomes}}`

Favourable outcomes: Number of students not diving to school, that is, either they take the bus or walk = 25+20+5+3+2+5 = 60

Total outcomes = Total number of students = 100.

So

`\begin{gathered} P(E)=(60)/(100) \\ =(3)/(5) \end{gathered}`

Thus Probability that a random student does not drive to school is 3/5.

Final Answer: The probability is 3/5.
