Supposed that voting in municipal elections is being studied and four people are randomly selected. The accompanying, table provides the probability distribution where x is the number of those people that voted in the last election

x | P (x)
0 | 0.23
1 | 0.32
2 | 0.26
3 | 0.15
4 | 0. 04

which result from the study would constitute an unusual event?
A) 4
B) 3
C) 2
D) 0
I think the answer is A but I am not sure

The probability of all four voting is 0.4

That is by far the lowest probability.
It also makes sense in our world.

Ah, the good old municipal elections, where the excitement is just riveting! Now, let's analyze this probability distribution and uncover which result would constitute an unusual event.

Looking at the probabilities, we can see that the probability of 4 people voting is a whopping 0.04. That's quite low! So, if 4 people actually voted in the last election, that would indeed be quite unusual.

Therefore, my dear friend, you are absolutely correct! The answer is A) 4. It seems like a rare occurrence, so keep an eye out for those dedicated voters!

To determine which result from the study would constitute an unusual event, we need to consider the probabilities associated with each result. The term "unusual event" typically refers to an event that has a low probability of occurring.

Looking at the given probability distribution:
P(0) = 0.23 (probability of 0 people voting)
P(1) = 0.32 (probability of 1 person voting)
P(2) = 0.26 (probability of 2 people voting)
P(3) = 0.15 (probability of 3 people voting)
P(4) = 0.04 (probability of 4 people voting)

A result can be considered unusual if its probability is significantly lower than the others.

In this case, the probability of 0 people voting (P(0) = 0.23) is the highest among all the options. Therefore, we can conclude that the most likely result is 0 people voting in the last election.

Conversely, the probability of 4 people voting (P(4) = 0.04) is the lowest among all the options. This implies that getting 4 people to vote would be an uncommon event, as it has a lower probability compared to the others.

Therefore, the correct answer is A) 4, as it represents an unusual event in this context.

To determine which result from the study would constitute an unusual event, we need to consider the probabilities associated with each outcome. An unusual event is generally considered to be one that has a low probability of occurring.

From the given probability distribution:

P(0) = 0.23
P(1) = 0.32
P(2) = 0.26
P(3) = 0.15
P(4) = 0.04

Among these probabilities, the lowest probability is associated with the outcome of 4 people voting in the last election, which is P(4) = 0.04.

Therefore, the answer is A) 4. This outcome has a lower probability compared to the others, making it an unusual event.
