I think they are asking no of element in GLB. 0 votes 0 votes Please log in or register to add a comment.

So by that method, we will get A : Please correct me if I am wrong. 0 votes 0 votes Arkaprava commented May 20, 2019 reply Follow Share Yes, the framing is pretty ambiguous. Your assumption regarding the question is correct, but how can you add sets ? 0 votes 0 votes Shawn Frost commented May 20, 2019 reply Follow Share @Arkaprava i mean to say summing the element in the set 0 votes 0 votes Arkaprava commented May 20, 2019 reply Follow Share This question is poorly framed The GBL set would comprise of {{$\varnothing$},{$x$},{$y$}}. My question is that the elements in the GBL are sets, we can't add sets. That is why I thought the answer should be 0. What is the explanation provided in the answer? 0 votes 0 votes Nikhil gate 2020 commented Oct 2, 2019 reply Follow Share Hasse diagram: Greatest Lower Bound of lattice is { } or ϕ Sum of elements in GLB of lattice = 0 in test book exp nothing is clear according to me x+y but it also true we not add set. i think question is wrongly frame. 0 votes 0 votes Please log in or register to add a comment.
