So five has more chancesStudent 6
For 5 – 1,4 / 2,3 / 3,2 / 4,1
For 10 – 4,6 / 5,5 / 6,4
As likely five has more chances of winningStudent 10
Chances of rolling 5:
1,4 (or vice-versa)
2,3 (or vice-versa)
= 2 chances
Chances of rolling 10:
4,6 (or vice-versa)
5,5
= 2 chancesTherefore, both 5 and 10 have equal chances of getting rolled.
