Given that C is a set of cities in England and x,y∈C. R is a relation on set C defined as (x,y)∈R if x is close to y, i.e. the straight line distance is less than 50km. The relation R is? reflexive / not reflexive? symmetric / not sysmmetric / antisymmetric ? transitive / not transivive? anyone has any idea on this question?

do you think that if A is less than 50km away from B, and B is less than 50km away from C, this means A must be less than 50km away from C? @jeqx

it should be not trainsitive, because if A is 50km away from B, and B is 30 km from Z, then A is actually 80km from Z , hence A is not close to Z, hence it is not transitive, is my logic correct or still wrong @Ann ? 🙂

it should be the case right? since it says we need to select 12 different type of donuts, which mean we can at most take one donut each type isn't it?

ah alright, so whenever we are dealing with selecting item which can be repeatedly of the same type , and the order does not matter, we will be using this formula?
