P (Blue Clothing or a Pair of Pants )  =  ????

P( Blue Clothing)  = 18/26

P( Pair of Pants)   = (14/26)

P( Blue Pair of Pants)  = 10/26     

 

So

 

Probability (Blue Clothing or a Pair  of Pants)  = P(Blue Clothing) + P (Pair of Pants) - P(Blue Pair of Pants)  =

 

18/26 + 14/26  -  10/26  =

 

22/26    =

 

11/13
