I need to know the whole thing please help

Answer 1

a) A student travelling to school on public transport: 15/52 or 0.231

b) A student walking to school: 16/52 or 0.308

c) A student not cycling to school: 43/52 or 0.827

Explanation:

Total people = 52

Travel Method Frequency

Public Transport 12

Car 15

Cycle 9

Walk 16

Find the relative frequency of.

The formula used will be:
`Relative\:Frequency=(Given\: Frequency)/(Size\: of\: sample \:space)`

a) A student travelling to school on public transport:

Given Frequency: 12

Size of sample space: 52

Apply formula:
`Relative\:Frequency=(Given\: Frequency)/(Size\: of\: sample \:space)`

Fraction = 12/52

Decimal = 0.231

b) A student walking to school

Given Frequency: 16

Size of sample space. 52

Apply formula:
`Relative\:Frequency=(Given\: Frequency)/(Size\: of\: sample \:space)`

Fraction = 16/52

Decimal = 0.308

c) A student not cycling to school.

We will consider all students except those who cycle.

12+15+16 = 43

Given Frequency: 43

Size of sample space. 52

Apply formula:
`Relative\:Frequency=(Given\: Frequency)/(Size\: of\: sample \:space)`

Fraction = 43/52

Decimal = 0.827
