Question 852488: the probability that a person will be right handed is 65%. Find the probility of that, if 5 people are selected, at least 1 will be left handed. Answer by ewatrrr(24785) (Show Source):
Hi,
Using TI P(x ≥ 1) The syntax is 1 – binomcdf(n, p, largest x-value).
p = .65, n = 5
P(x ≥ 1) = 1 – binomcdf(5,.65,0)
0r using where p and q are the probabilities of success and failure respectively.
P(x ≥ 1) = 1 - P(0)= 1 - (.35)^5
