Answer:
- <u>Third choice: {3, 4, 6, 7, 9}</u>
Explanation:
<em>M ∪ N</em> means the union of the segments M and N. That is, the complete list of objects that are either in the set M or N.
The circle on the left of diagram shows that the elements inside the set M are 3, 4, 7 and 9.
The circle on the right of the diagram shows that the elements inside the set N are 4, 6 and 7.
The complete list of the numbers in either M or N is 3, 4, 6, 7, and 9 (you must not repeat the elements that belong to both sets but indicate them just once.
So, the set that represents M ∪ N is the third option {3, 4, 6, 7, 9}.
Step-by-step explanation:
1.) Firstly, you need to count out how many things there are. 4 app, 5 entrees, 2 desserts. This makes 11 different things
2.) for 11 numbers there can be 9 ways for each number for 1st nine places since 0 can't be the fist figure and next two are reciprocated from 10 numbers. Therefore 10!/2!
3.)So 99 combinations have 10!/2! Permutations hence total ways are 99*10!/2!
