Answer:
The probability that the system is a Wii console is 0.46
Step-by-step explanation:
Probability expresses the possibility of an occurrence of an event. The probable outcomes for the event is called sample space.
For the given question,
Number of Sony Playstations = 6
Number of Nintendo Wii consoles = 5
Total number of games on the shelve = 11

pr(the system is a Wii console) = 
= 0.4555
≅ 0.46
The probability that the system is a Wii console is 0.46.
