Question 762538
 It is believed that 55% of the eligible voters in the U.S. will vote on election day. If four eligible voters are randomly selected, what is the probability at least one will vote on election day?
-------------------------
Binomial problem with n = 4 and p(vote) = 0.55 ; p(not vote) = 0.45
----------------------------
P(x>=1 votes) = 1 - P(none of 4 votes) = 1 - (0.45)^4 = 1- 0.0410 = 0.9590
