Question 359007

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^x}}}*{{{q^(n-x)}}} 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* {{{.5^5}}}*{{{.5^(9)}}}
n = number of trails = 14
x = number of successes = 5
p = as stated above = .5
