Hi,

p = .08,  n = 13

using TI Calculator

P(x=3) = The syntax is binompdf(n, p, x-value)= binompdf(13, .08,3)

Or

 P = (.08)^3(.92)^10  

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

P (x)=  (p)^x(q)^(n-x) where p and q are the probabilities of success and failure respectively. 

In this case p = .08 & q  = .92

 =  

 =
