Note :

 

Mult of 2  = 2, 4, 6

Mult of 3  =  3,6

Multiple of 2 and 3  =  6

 

 

 

Prob ( Multiple of 2  or Multiple of 3)  =

 

Prob of Mult of 2 = ( 3/6)   + Prob of Mult of 3 = (2/6)  - Prob of Mult of 2 and 3 =  (1/6)  =

 

(3/6) +  ( 2/6) - (1/6)  =    

 

5/6 - 1/6  =

 

4/6   =

 

2/3
