Question 1197154
<pre><font face = "consolas" color = "indigo" size = 3><b>
Binomial distribution:  p = .44 , n=7
Find P(4)

Using Formula (Recommend Using stattrek.com to check results)
Using {{{P (x)= highlight_green(nCx)(p^x)(q)^(n-x) }}} 
p and q are the probabilities of success and failure respectively. 
p = .44 , q = .56  {{{nCx = (n!)/x!(n - x)!)}}} = 35 (Using nCr button on Calculator)
{{{P (4)= highlight_green(35)(.44^4)(.56)^(3) }}} = .2304

Using TI or similarly an inexpensive calculator like an Casio fx-115 ES plus
P(x) is binompdf(n, p, x-value).
P(4) = binompdf(7, .44, 4)= .2304

Feeling comfortable with Your calculator is key to Your success working
with the various Distributions.
