Six hundred paving stones were examined for cracks, and 15 were found to be cracked. The same 600 stones were then examined for
9966 [12]

Answer: 0.01

Step-by-step explanation:

Let the events are :

C = paving stones found to be cracked.

D = paving stones found to be discolored.

Given : Total stones : T = 600  (i)

C = 15

D=  27

C'∩D'=  564   (ii)

Since C'∩D' = (C∪D)' = T- C∪D         (iii)

From (i) , (ii)and (ii) , we have

564 = 600- C∪D

⇒ C∪D=600- 564= 36

Formula : C∩D= C+D- C∪D

Put values , we get

C∩D= 15+27-36=6

Now ,

P(C\cap D)=\dfrac{C\cap D}{T}=\dfrac{6}{600}=0.01

The probability that it is both cracked and distorted is 0.01.
