Question

On a particular day, at a crossing in a city, the various types of 240 vehicles going past during a time interval were observed as under:
$\begin{array}{cccc}\text{Type of vehicle}& \text{Two-wheelers}& \text{Three-wheelers}& \text{Four-wheelers}\\ \text{Frequency}& 84& 68& 88\end{array}$

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

• A. $\frac{3}{20}$
• B. $\frac{11}{20}$
• C. $\frac{7}{20}$
• D. $\frac{9}{20}$

Answer 1

The correct option is C

$\frac{7}{20}$

Number of two wheelers = 84
Total number of vehicles = 240
Probability of a two wheeler = $\frac{84}{240}=\frac{7}{20}$.
