You can put this solution on YOUR website! How do I get P(X=x) in the following question?
Andy Dalton has 62% chance of completing any individual pass. Let X be the number of passes he completes in his next four attempts. Determine the probability distribution of X.
-------
It's Binomial because he either completes or does not complete each pass.
----------
P(X = x) = 4Cx(0.62)^4*(0.38)^(4-x) for x = 0,1,2,3,4
------------
Example:
P(X = 3) = 4C3(0.62)^3(0.38) = binompdf(4,0.62,3) = 0.3623
