We have P ( even number on first die ) $ = \large\frac{1}{12}$

P ( total of 8 ) = $ \large\frac{5}{36}$

and P ( even number on first die and a total of 8 ) = $ \large\frac{1}{12}$

Using addition theorem of probability we have P ( even number on

first die or a total of 8 )

$ = \large\frac{1}{2} + \large\frac{5}{36}-\large\frac{1}{12}$

$ = \large\frac{5}{9}$
