Given the events below, determine which equation correctly calculates the probability of drawing two kings in a row from a standard 52-card deck, without replacement.

event a: the first card drawn is a king.
event b: the second card drawn is a king.

a. p(a n b) = p(a) * p(b|a)

b. p(a n b) = p(a) * p(b)

c. p(a n b) = p(a) * p(a|b)

d. p(a n b) = p(b) * p(b|a)
