I can do a couple of them.....

 

Flip a coin....roll a 6 sided die

 

P ( Heads  and < 6)  =   (1/2) * (5/6) =    5 / 12

Last one

 

P(A)  = 60 / 150 =   6/15  =  2/5

P(B) =  50 / 150  =  5 / 15  =  1/3

P(A and B) =  (2/5)(1/3) =  2 / 15

 

P(A l B)  =   P (A and B)                (2/15)

                  __________   =         _______   =       (2/15) * (3/1) =   6/15 =   2/5

                      P(B)                          (1/3)       

 

P(A l B )  = P(A)  is true.....the events are independent
