<PRE><B>Question 760642</B>
the proper formula to use on the following 
at Least Once Problem: 
meeting at least one left handed person in eight random encounters on campus when the incident rate is 11% (11 in 100 are left handed). 
------
Binomial Problem witn n = 8 and p(left) = 0.11
----
P(at least one left handed) = 1 - P(no left handed)
------
= 1 - 0.11^8
-----
= 1 - 0.0000000214
