Question

plz answer qus no. 30

Answer 1

Step-by-step explanation:

now 45 people use vehicles

1 ) so motorcycle users will be

45- ( 17 +8)

= 20

so probablity = favourable/ total

= 20/45

= 4/9

will be probablity of motorcycle

2) now 5 people in 1 car

so in 8 cars = 8× 5= 40

so 40 people will go by car

so probablity = 40/45

= 8/9

3) people not going by car = 45- 40

= 5

so probablity of non going = 5/45

= 1/9

4) In 2nd statement people are aware about preserving quality of environment as if everyone will use their own vehicles it will cause pollution in huge ammount
