Answer:
7/11
Explanation:
You want to know the probability that a randomly chosen number on the given diagram is not in set Q.
Numbers
There are 11 numbers on the diagram (1–12 except 5). Of those, 4 are in set Q, so 11 -4 = 7 are not in set Q.
If a number is randomly chosen, the probability it is not in set Q is ...
(numbers not in Q)/(number of numbers) = 7/11
