Question 1127463: Suppose we want to determine the
(binomial) probability (p) of getting 4
heads in 10 flips of a 2-sided coin. Using
the Binomial Table in the appendix of the
text, what values of n, x, and p would we
use to look up this probability, and what
would be the probability?

You can put this solution on YOUR website! Suppose we want to determine the

-----
n is the number of trials:: 10
p is the probability of getting "head" in one trial:: 1/2
x is the # of heads in the 10 trials:: 4
-----
P(x=4) = 10C4*(1/2)^4*(1/2)^6 = binompdf(10,1/2,4) = 0.2051
