Answers
train used to transport goods and bus,cars are used to travel people
Given : different mode of transport used by the people
To Find : probability of number of people:
(a) Used car and scooter only
(b) Used cycle only
(c) Used at least one kind of mode of transport.
(d) Used public transport
(e) Used two wheel vehicle
Solution:
Mode of transport Number of people
car 80
scooter 120
Bus 100
Train 70
cycle 110
No transport 20
TOTAL 500
(a) Used car and scooter only
80 + 120 = 200
Probability = 200/500 = 2/5 = 0.4
(b) Used cycle only
Probability = 110/500 =11/50 = 0.22
(c) Used at least one kind of mode of transport.
= Total - No transport required
= 500 - 20
= 480
Probability = 480/500 = 24/25 = 0.96
(d) Used public transport
BUS + Train = 100 + 70 = 170
Probability = 170/500 = 17/50 = 0.34
(e) Used two wheel vehicle
Scooter + cycle = 120 + 110 = 230
Probability = 230/500 = = 23/50 = 0.46
