why does the probability of a success in a binomial experiment have to remain constant?

If it's everchanging then you can't neccessarily calcualte anything.
-Is that a decent explanation......I know that the prob of success definitely has to be constant, it's just hard to explain.
 
One reason it remains constant is because replacement is assumed. If there were no replacenment, then the probabilities would change at each trial. This would be a hypergeometric probability, not binomial.
