From a pack of 52 cards,two cards are drawn at random together at random what is the probability of both the cards being kings?	Pick.
A) 1/221  B) 8/221  C) 4/589  D) 4/587  E) 7/654
let S be the sample space then   n(S)=52C2=(52*51)/(2*1)= 
<gadget id="calculator">(52*51)/(2*1)</gadget>
<output>1_326</output>
1326   let E be the event of getting 2 kings out of 4   n(E)=4C2=(4*3)/(2*1)= 
<gadget id="calculator">(4*3)/(2*1)</gadget>
<output>6</output>
6   P(E)=n(E)/n(S)=6/1326=1/221   1/221nswer (1/221)
