Solution

Question 2:

Following is the completed table:

(a)

Out of 100 people, 30 uses cell phone while driving so the required probability is 30/100.

(b)

There are 20 people out of 100 is in state without law AND uses their cellphone while driving. So the required probability is 20 /100.

(c)

There are 10 people out of 100 is in state with law AND uses their cellphone while driving.

So

P(law and use cell phone) = 10/100

P(law) = 50/ 100

So the required probability is

P(use cell phone | law) = P(law and use cell phone) / P(law) = 10/50

	Use cell phone while driving	Do not use cell phone while driving	Total
Law	10	40	50
No law	20	30	50
Total	30	70	100
