help pleaseeeee :) 1. Let set A = {odd numbers between 0 and 100} and set B = {numbers between 50 and 150 that are evenly divisible by 5}. What is A ∩ B? 2.Let set C = {1, 2, 3, 4, 5, 6, 7, 8} and set D = {2, 4, 6, 8} Which notation shows the relationship between set C and set D?

1. If it is intersection then it SHOULD be included in both the sets right? Now we know that odd numbers from 1-100 but the second set are multiples of 5 from 50-150! So we mainly need to look for common numbers which are ODD and are a MULTIPLE OF 5 BETWEEN 50 - 100!! So A={51,53,57,59,61......99} B={55,60,65,70.......95} [We stop till 100 because set A has no such element] So what is A ∩ B here? A ∩ B = {All odd numbers and multiples of 5 between 50 - 100} 2. If we see here, D has all the elements which ARE in C!! So can we not say that D is a subset of C? :) Understood both of them? :)
