Answer:
d. 20+10+5+2.5+...
Step-by-step explanation:
No geometric series with a common ratio of magnitude greater than 1 will have a finite sum. Nor will any arithmetic series.
Those descriptions exclude answer choices a, b, c. Choice d is a geometric series with a common ratio of 1/2, so will have a finite sum. (It is 40.)
Let be the amount of food needed for one man for one day. At the beginning, we have enough food for 400 men for 40 days, i.e.
After 10 days, the 400 men will have consumed
food, impliying that the food remaining is
If 200 more men join the garrison, there are now 600 men. Each of them requires food each day, and there are units of food remaining. They will last
days.

Answer:
Theoretical probabilities are the long-run relative frequencies based on an experiment.
Step-by-step explanation:
Relative frequency or experimental probability is calculated from the number of times an event happens, divided by the total number of trials in an actual experiment.
With theoretical probability, you don't experiment. Instead, you use what you know about the situation to determine the probability of an event occurring.
Experimental probability approaches theoretical probability when the number of trials is extremely large.
Therefore, theoretical probabilities are the long-run relative frequencies based on an experiment.
