Please help me solve this question:
List the elements of each of the following sample spaces:
(a) the set of integers between 1 and 50 divisible by 8;
(b) the set S = {x | x2 + 4x − 5=0};
(c) the set of outcomes when a coin is tossed until a tail or three heads appear;
(d) the set S = {x | x is a continent};
(e) the set S = {x | 2x − 4 ≥ 0 and x < 1}.

As I see from your post, you have serious problem with the language.
This phrase/wording " solve this question " is not used neither in English nor in any other human language on the Earth,
because these words " solve " and " question " are never used in such combination.
Only mafia (in numerous videos) uses such a jargon.
If you want your writing to look decent, don't use this jargon " solve question ".
(a) 8, 16, . . . continue to add 8 to the previous number to get the next number until you get more than 50.
(b) Solve quadratic equation x^2 + 4x - 5 = 0 to find its roots.
The simplest way is to factor (x+5)*(x-1) = 0; the roots are -5 and 1.
So, the set S is {-5,1}.
(c) The set of outcomes is { T, HT, HHT, HHH }.
Here T denote outcome "tail"; H denote outcome "head".
It is enough to think 1.5 minutes to get it.
(d) This question relates to Geography.
(e) This set of x is empty, since if x < 1, then 2x-4 < 2*1 - 4 = -2 and can not be greater than or equal to 0 (zero).
Solved.
