5/12

Step-by-step explanation:

Notice that the in the throw of a pair of dice.

Sum               No. of times Favorable outcome

8                                 5

9                                  4

10                                 3

11                                  2

12                                 1

And total otcome = 6×6 =36

There P ( richard win) = P(X≥8)

=  (5+4+3+2+1)/36

=5/12

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
