Answer: The probability that both the television set be defective would be 7/1,912.
Step-by-step explanation:
Number of defective televisions= 15
Number of total televisions= 240
So,
The probability that the first television set be defective P(A)=15/240=1/16
The probability that the second television set be defective provided first is defective, P(B|A)= 14/239
The probability that both the televisions are defective, P(AUB)=P(A)*P(B|A)=15/240*14/239
=> 7/1,912
