To find the number of people that would be expected to die if there is a death rate of 5 in every 100 people and a population of 175,000, we can use the formula for expected value:

Expected value = (probability of event occurring) * (value of event occurring)

In this case, the probability of a person dying is 5/100 = 0.05, and the value of a person dying is 1 (since one person dies each time the event occurs). Therefore, the expected value is 0.05 * 1 = 0.05.

Since there are 175,000 people in the population, we can multiply the expected value by this number to find the total number of people that would be expected to die: 0.05 * 175,000 = 8750.

Therefore, we would expect a total of 8750 people to die if there is a death rate of 5 in every 100 people and a population of 175,000.
