P ( S  or T )  = P (S)  + P(T)  -  P (P and T)

 

Since they are mutually exclusive, P( P and T)  = 0

 

So

 

P (S or T)  = P(S) + P(T)  =  .20  + .22  =   .42

 

 

5.

We have 22 objects in total

P( Green or Cube)  = P(Green)  + P (Cube)  - P (Green and Cube)

 

                               =   11/22     +  12/22   -   5/22

 

                              =  18/22      

 

                                =  9/11
