Find the relative frequency of.
The formula used will be:
a) A student travelling to school on public transport:
Given Frequency: 12
Size of sample space: 52
Apply formula:
Fraction = 12/52
Decimal = 0.231
b) A student walking to school
Given Frequency: 16
Size of sample space. 52
Apply formula:
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:
Fraction = 43/52
Decimal = 0.827

Answer:
10 adults
Step-by-step explanation:
1 adult per 6 children
there already 1 adult per class so 6 children from each class are covered
24 - 6 = 18
26 - 6 =20
28 - 6 = 22
18 + 20 + 22 = 60
60 ÷ 6 = 10
so 10 more adults are needed
