Question

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

Answer 1

Answer:

Lets assume a case:

Number of 2 wheelers passed =18

Number of 3 wheelers passed =23

Number of 4 wheelers passed =19

The time interval is 15 minutes for all the 3 conditions.

Total number of vehicles passed = Number of 2 wheelers + Number of 3 wheelers + Number of 4 wheelers

=18+23+19=60

Probability that one vehicle out of total vehicles is 2 wheelers =

60

18

=

10

Answer 2

The question is an activity to be performed by the students.

Hence, perform the activity by yourself and note down your inference.
