Answer: The probability that both televisions work is
The probability at least one of the two televisions does not work is .
Step-by-step explanation:
Given : Number of televisions received = 8
Number of defective televisions=3
Number of good television = 8-3= 5
Then , the number of ways to select any two television out of 8 =
The number of ways to select two working televisions out of three =
Now , If two televisions are randomly selected, the the probability that both televisions work
Hence, the probability that both televisions work is
Also , the probability at least one of the two televisions does not work = 1- P( both televisions work)
Hence, the probability at least one of the two televisions does not work is
