If a is the set of all even numbers from 10 to 20 and b is the set of ...
Explanation:
Determining if events ab and c are mutually exclusive:
- Event ab represents the intersection of sets a and b, i.e., the even prime numbers in the range of 10 to 20.
- Event c represents the element 15, which is neither even nor prime.
Understanding mutually exclusive events:
- Two events are said to be mutually exclusive if they cannot occur at the same time.
- In other words, if one event happens, the other event cannot happen simultaneously.
Analysis:
- In this scenario, the elements of set a (even numbers) and set b (prime numbers) do not overlap.
- The set of even numbers from 10 to 20 is {10, 12, 14, 16, 18, 20}.
- The set of prime numbers from 10 to 20 is {11, 13, 17, 19}.
- The intersection of sets a and b (event ab) is an empty set as there are no numbers that are both even and prime in this range.
- Therefore, event ab and event c (element 15) are mutually exclusive because there is no common element between them.
Conclusion:
- Based on the analysis, it can be concluded that events ab and c are mutually exclusive in this scenario.
- This understanding is crucial in probability theory and helps in calculating the likelihood of various outcomes in different situations.
