Question 359007: Suppose we want to determine the (binomial) probability(p) of getting 5 heads in 14 flips of a 2-sided coin. Using the Binomial Probabilities Table 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?

Hi,

(binomial) probability(p) of getting 5 heads in 14 flips of a 2-sided coin. 



Note: The probability of x successes in n trials is: 

.

P = nCx* p%5Ex*q%5E%28n-x%29 where p and q are the probabilities of success and failure respectively. 

In this case both p & q are = 1/2 or .5





P( 5 heads in 14 flips of a 2-sided coin) = 14C5* .5%5E5*.5%5E%289%29

n = number of trails = 14

x = number of successes = 5

p = as stated above = .5
