Four cards drawn from standard denk of cards.Each card is replaced before the next one is drawn .Find each probability.
----
Binomial Problem with n = 4 and p = 4/52 = 1/13
---------------
P(at most 1 jack) = P(x=0)+P(x=1) = (12/13)^4 + 4(1/13)(12/13)^3 = 0.7383
-------------------
P(4 jacks ) = (1/13)^4
------------------------
P(exactly 3 jacks) = 4C3(1/13)^4*(12/13) = 0.0469
