What information must be known in order to use the binomial probability distribution to calculate the probability that a particular kind of golf ball will be removed from its approved-ball list?

To see if you can use a binomial, remember BINS

B - is it binomial (either it is approved or not)

I - independent (one type being approved doesn't affect another)

N - number of trials is set (not really known from info given)

S - success (chance of each type of golf ball being chosen is the same)
