PLEASE ANSWER ASAP suppose 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 voted in the last election. which result from the study would constitute an unusual event

E(x) = 1.45

Since the expected value is 1.45 therefore, it will be very unusual to find 4 voters among the four randomly selected people.

Step-by-step explanation:

The expected value is given by

Since the expected value is 1.45 therefore, it will be very unusual to find 4 voters among the four randomly selected people.

Therefore, the last option is the correct that is 4.

which expression represents the approximate length of bc?

step-by-step explanation:

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %  

step-by-step explanation:
