20 throws of a die produces following results
SCORE -- NUMBER OF OCCURRENCES
---1-------------------4
---2-------------------3
---3-------------------5
---4-------------------2
---5-------------------2
---6-------------------4
What is the probability M that one more throw to this series will increase the mean score? Select the correct option:	A) 1/6	B) 1/3	C) 1/2	D) 2/3	E) 5/6
I get the mean as 67/20 --&gt; 3.35. Thus in order to raise this mean we would need a 4,5,or 6.   Thus probability Mis 1/2.1/2
