On a particular day, at a crossing in a city, the various types of vehicles going past during a time interval were observed as follows:
Type of vehicleTwo-wheelersThree-wheelersFour-wheelersFrequency846888
Out of these vehicles, one is chosen at random. What is the probability that the chosen vehicle is a two-wheeler?
720
Probability = Number of favourable outcomesTotal number of outcomes
Number of two wheelers = 84
Total number of vehicles = 84 + 68 + 88 = 240
Probability of a two wheeler = 84240=720.
