Question

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:
$\begin{matrix} Type of vehicle & Two-wheelers & Three-wheelers & Four-wheelers Frequency & 84 & 68 & 88 \end{matrix}$

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

Solution

The correct option is B
$\frac{7}{20}$

Probability = $\frac{N u m b e r o f f a v o u r a b l e o u t c o m e s}{T o t a l n u m b e r o f o u t c o m e s}$

Number of two wheelers = 84

Total number of vehicles = 84 + 68 + 88 = 240

Probability of a two wheeler = $\frac{84}{240} = \frac{7}{20}$ .

The correct option is B 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.

The correct option is B
$\frac{7}{20}$

Probability = $\frac{N u m b e r o f f a v o u r a b l e o u t c o m e s}{T o t a l n u m b e r o f o u t c o m e s}$

Number of two wheelers = 84

Total number of vehicles = 84 + 68 + 88 = 240

Probability of a two wheeler = $\frac{84}{240} = \frac{7}{20}$ .
