Question

On a particular day, at a crossing in a city, the various types of 24 vehicles going past during a time interval were observed under:

Types of vehicle	Two-wheelers	Three-wheelers	Four-wheelers
Frequency	84	68	88

Out of these vehicles, one is chosen at random. What is the probability that the chosen vehicle is a two-wheeler?

Answer 1

It is given that

Number of vehicles = 240

Number of two wheelers = 84

We know that

Required probability = number of two wheelers/ number of vehicles

By substituting the values

Required probability = 84/240

By division

Required probability = 0.35
