Type of vehicleTwo - wheelersThree - wheelersFour - wheelersFrequency846888
what it is the probability that a selected vehicle is a two-wheeler?
ANSWER:
Total number of vehicles going past the crossing = 240
Number of two-wheelers = 84
Let E be the event that the selected vehicle is a two-wheeler. Then,
required probability = P(E) = 84240=0.35
