Hi,

Using TI: The syntax is binompdf(n, p, x-value).

 p = .3,   n = 12

P(x=4) = binompdf(12,.3,4)= .2311



Using: P+%28x%29=+highlight_green%28nCx%29%28p%5Ex%29%28q%29%5E%28n-x%29+ 

P+%284%29=+highlight_green%2812C4%29%28.3%5E4%29%28.7%29%5E%288%29+ 

P+%284%29=+highlight_green%28495%29%28.3%5E4%29%28.7%29%5E%288%29+
