Find the probability of randomly drawing four aces in succession from an ordinary deck of 52 playing cards, if we sample with replacement.

K_1={drawing an ace in the first draw}
K_2={drawing an ace in the second draw}
K_3={drawing an ace in the third draw}
K_4={drawing an ace in the fourth draw}
K_1,K_2,K_3,K_4  are independent
P(K_1∩K_2∩K_3∩K_4 )=P(K_1 ).P(K_2 ).P(K_3 ).P(K_4 )=4/52*4/52*4/52*4/52
