Suppose we want to determine the (binomial) probability (p) of getting 2 heads in 5 flips of a 2-sided coin. Using the Binomial Table (Table 2 in Appendix B) of the text, what values of n, x, and p would we use to look up this probability, and what would be the probability?
thank you in advance

-------
P(x=2) = 5C2(1/2)^2*(1/2)^3 = 10/32 = 0.3125
