One card is drawn from a pack of 2 cards. The probability that it is the card of a king or spade is
a. 1/26    
  b. 3/26   
    c. 4/13 
  d. 3/13

Explanation

If `A` and `B ` denote the events of drawing a king and a spade card, respectively,
then event A consists of four sample points,
whereas event B consists of `13` sample points.


Thus, `P(A)=4/(52)` and `P(B)=(13)/(52)`


The compound event (A∩B) consists of only one sample point, king of spade


So, `P(A∩B)=1/(52)`
