Two cards are drawn together from a pack of 52 cards the probability that one is the spade and one is a heart is ?  Choose the most appropriate option
A) 85/852	B) 45/69	C) 18/456	D) 13/102	E) 23/125
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 1 spade kings and 1 heart   let n(E)=number of ways of chossing 1 spade out of 13 and 1 heart out of 13=(13C1*13C1)=13*13= 
<gadget id="calculator">13*13</gadget>
<output>169</output>
169   P(E)=n(E)/n(S)   =169/1326   =13/102 Answer(13/102)
<result>D</result>
