An abelian group is a group in which the group operation is commutative, meaning that for all elements a and b in the group, a * b = b * a. To determine if n is an abelian group, we need to know the specific group operation and the set of elements in the group. Without this information, we cannot definitively say whether n is an abelian group. However, if the group operation is commutative for all elements in the set, then n would be an abelian group. **

P is in the age group of 25-30 years old. **

A randomly selected person from group A would count as a person from group A (P(A|B)), as the probability of being from group A given that they were randomly selected is what is being calculated. P(A|B) represents the probability of event A occurring given that event B has occurred. Therefore, in this case, the focus is on the probability of being from group A given that the person was randomly selected. **

A randomly selected person from group A counts as a person from group A (P(A|B)), because the probability notation P(A|B) represents the probability of event A occurring given that event B has already occurred. In this case, event B is the person being randomly selected, and event A is the person being from group A. Therefore, P(A|B) represents the probability of a randomly selected person being from group A. **

One can contribute to retirement savings by setting up a retirement account such as a 401(k) or an Individual Retirement Account (IRA) and making regular contributions to it.
