Discussion Overview

The discussion centers around the probability of rolling a sum of 12 with two dice and the number of rolls required to achieve a probability greater than 1/2 for this outcome. The conversation also touches on the terminology used in reference to dice.

Discussion Character

  • Exploratory, Debate/contested, Meta-discussion

Main Points Raised

  • One participant asks how many times two dice need to be thrown to achieve a probability greater than 1/2 of rolling a sum of 12.
  • Another participant inquires about the distribution of outcomes when rolling two dice, suggesting a need for further exploration of the topic.
  • Several participants engage in a discussion about the correct terminology, specifically the use of "dices" versus "dice," with some asserting that "dice" is already plural and should be used in the context of two dice.
  • There is a contention regarding the comparison of "two dice" to "two shoes," with participants debating the grammatical correctness of the term "dices."

Areas of Agreement / Disagreement

Participants generally disagree on the grammatical usage of "dices," with some insisting on the correctness of "dice" as the plural form, while others seem to accept the common usage of "dices." The probability question remains unresolved, with no consensus on the number of rolls needed.

Contextual Notes

The discussion lacks a clear mathematical framework or calculations regarding the probability of rolling a sum of 12, and assumptions about the distribution of outcomes are not fully articulated.

How many times do we need to throw 2 dices to get more than 1/2 probability that at least once the sum of the two dices will be 12.

Well, what do you know about the distribution of "two dice"?
 
And my standard complaint: "dices" is a verb. "dice" is itself already plural- it is the plural of the word "die". You mean to say "two dice".

Same as "two shoes". Common usage.
 
No, it is not the same. "Two shoes", yes. "Shoes" is the plural of "shoe" But not "two dices" because "dice" is already plural. It should be "two dice".

Right. Dice is plural. Are you sure it's a grammar error from the OP and not just falling asleep on the keyboard?
