Answer: 240
Step-by-step explanation:
As per given ,
Number of choices for Receiver = 5
Number of choices for CD Player= 4
Number of choices for Speakers = 3
Number of choices for Cassette Deck =4
If a switch board display in the store allows a customer to hook together any selection of components , then by product rule
The number of ways one component of each type be selected = (Number of choices for Receiver) x (Number of choices for CD Player) x (Number of choices for Speakers )x (Number of choices for Cassette Deck)
= 5 x 4 x 3 x 4 = 240
Hence, the answer is 240.
