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

1 answer

The probability of all four voting is 0.4
That is by far the lowest probability.
It also makes sense in our world.
