2 * 2 * 2 = 8 combinations.

• 777
• 778
• 787
• 788
• 877
• 878

• 777
• 778
• 787
• 788
• 877
• 878
• 887
• 888

But 778 is the same as 787 is the same as 877
788 is the same as 878 is the same as 887

Statistically not. When counting the probability of a certain combination, then you need to count every disk having 2 possibilities, giving the formula 2*2*2 = 8 = 2³. Statistically 778 is not the same as 787 or 877 when analyzing results.

True in a way but please read the puzzle again. Forget numbers and look at the puzzle as it is written. There are four ways the discs can land
1) three sevens
2) three eights
3) two sevens and one eight
4) two eights and one seven

Answer four
Q.E.D.
