On a particular day, in a city, 240 vehicles of various types going past a crossing during a time interval were observed, as shown:

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 given vehicle is a two-wheeler?

Solution

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) = $\frac{84}{240} = 0.35$ Number of unit tests in which he got more than 60% marksTotal number of unit tests = 26 = 13
