Dice Proposition (Posted on 2003-02-22) Difficulty: 5 of 5
If a pair of dice are thrown repeatedly until a 7 is thrown, what is the probability that all the other possible numbers from 2 through 12 will have been thrown by the time the 7 has been thrown? As a preliminary, what is the probability that 2, 11 and 12 will all have been thrown before the first 7?

Hints/Tips one more mehtod....... | Comment 2 of 5 |
we can also solve the problem by using the classical definition of probability and other properties..........but i think that this method will be a bit lengthy than that method when we are using the " Bernoullian Sequence " for a finite number of trials...........
