Answer:
Step-by-step explanation:
According to the mentioned information, the sample space of the experiment is as follows: S= {7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18} The outcomes of the event E are as follows: E = {7, 8, 9, 10, 11, 12} Therefore, the outcomes of Ec can be calculated as:
= {xlx ∈ S , x ∉ E}
Ec = {13, 14, 15, 16, 17, 18}
The outcomes of are {13, 14, 15, 16, 17, 18} .
The obtained outcomes of the set Ec are {13, 14, 15, 16, 17, 18} . These are calculated by subtracting the outcomes of the event E from the elements of sample space S.
