Activity :- Note the frequency of two-wheeler three-wheeler and four-wheelers going past during a time interval, in front of your school gate. Find the probability that any one of the vehicles out of the total vehicles you observed is a two Wheeler.

Solution

After observing in front of the school gate
from time interval 6:30 to 7:30 A.M the respective frequencies of different
types of vehicles are:

Two wheelers =550

Three wheelers= 250

Four wheelers=80

The total number of vehicles = 550 + 250 + 80 =
880

Number 0f two wheelers=550

Hence, probability of observing two
wheelers=number of two wheelers/total number of vehicles= 550/880=5/8

Probability of observing two wheelers, P(2 Wheelers)= 5/8
Note- we have assumed certain things as it is activity

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?
