The answer is A. The sample space of an experiment or random trial is the set of all possible outcomes and results of that experiment, which means that they will be unique outcomes.
If five is a factor, it means that number can be evenly divided by five. Think about it like you're counting by fives or doing the fives times tables.
5, 10, 15, 20, 25, 30, 35, 40, 45, 50 etc.
As you can see, the only numbers that are in the ones place are 5 and 0.
Hope that helps!

Answer:
See below
Step-by-step explanation:
25¹¹ - 5¹⁹
Convert to base 5 = (5²)¹¹ - 5¹⁹
= 5²² - 5¹⁹
Factor out the GCF = 5¹⁹(5³ - 1)
= 5¹⁹(125 - 1)
= 5¹⁹ × 124
= 5¹⁹ × 4 × 31
31 is a factor of 25¹¹ - 5¹⁹, so the expression is divisible by 31.
