In Locality$-$sensitive Hashing $($LSH$),$ the function p $=1(1$s r $)$ b gives the probability p that two minhash signatures coming from sets with Jaccard similarity s will hash to the same bucket at least once. Consider we use an LSH scheme with b bands of r rows each for the minhash signatures of length $24.$ For a given similarity threshold s$,$ we want to choose b and r to maximize p$.$

$1.$ What are the possible value combinations of b and r in this LSH scheme $(5$ points$)?$
