question no 9 and 10

Dear Student,

Such questions are made for enhancing the self creative skills and should be tried answering on your own. However, here are a few points that will help you in framing your answer :

1 ) We can observe number of vehicles passed in front of school gate ( Let we observe in between 9 : 00 AM to 11 : 00 AM ), As :
 

Type of vehicle	Number of vehicle ( Frequency )
2 - wheelers	120
3 - wheelers	30
4 - wheelers	50
	Total = 200

We know probability P ( E )  =   $\frac{\mathrm{Total} \mathrm{number} \mathrm{of} \mathrm{desired} \mathrm{events} \mathrm{n} ( \mathrm{E} )}{\mathrm{Total} \mathrm{number} \mathrm{of} \mathrm{events} \mathrm{n} ( \mathrm{S} )}$

So,

Probability of one of the vehicle out of total vehicles is a 2-wheelers  = $\frac{120}{200} = \frac{\mathbf{3}}{\mathbf{5}}$                                         ( Ans )
