From a pack of 52 cards, 4 are drawn one by one without replacement. Find the probability that all are aces (or, kings).

Explanation

Consider the given events.

`A=`An ace in the first draw

`B=`An ace in the second draw

`C=`An ace in the third draw

`D=` An ace in the fourth draw

Now,

`P(A)=frac{4}{52}=frac{1}{13}`

`P(B | A)=frac{3}{51}=frac{1}{17}`
