Alice rolls a pair of fair six-sided dice until a sum of 6
appears for the first time. Independently, Bob rolls two fair
six-sided dice until he rolls a sum 7 for the first time. Find the
probability that the number of times Alice rolls her dice is equal
to or within one of the number of times Bob rolls his dice.
You toss a pair of fair six-sided dice 30 times. What is...
The probability that none of the 30 throws give a total of
12?
The probability that a total of 7 appears 5 or more times?
Consider the game consisting of rolling a pair of fair 6-sided
dice and recording the sum. It will cost you $1 to play the game.
If the sumis less than 5, then you will win $3. However, you do not
get your $1 back so your profit is $2. If you roll a sum of
exactly8, thenyou will win $4. However, you do not get your $1 back
so your profit is $3. Otherwise, you lose your $1.
A.What is...
Suppose that a game of chance is played with a pair of fair
10-sided dice (with the sides numbered 1 to 10). In the game, you
can pick any number from 1 to 10 and the two dice are then “rolled”
in a cage. If $1 is bet and exactly one of the number that you
picked is rolled you win $1, and if both of the dice are the number
that you picked you win $20 (in each of...
A fair six-sided die is rolled repeatedly until the third time a
6 is rolled. Let X denote the number of rolls required until the
third 6 is rolled. Find the probability that fewer than 5 rolls
will be required to roll a 6 three times.
Consider a six-sided fair dice. Complete the following tables
for this die:
Number on the dice
Number of times it appears on the dice
Relative frequency of seeing that number
1
2
3
4
5
6
Total
This is the entire question, does not say how many times the
dice is thrown
(5) A fair 6-sided dice is rolled twice. The fairness of the
dice consists of the following facts: (i) no face of the dice is
likelier to be rolled than any other (so a roll of a 5 and a roll
of a 3 are equiprobable) and (ii) the dice has no “memory” - each
roll is independent of any other. 5.1:
What is the probability that you’ve first rolled a 3 and the
pair of rolls sums to something...
When two fair six-sided dice are simultaneously thrown, these
are two of the possible results that could occur: Result 1: a 5 and
a 6 are obtained in any order. result 2: a 5 is obtained on each
die. Which of the following statements is correct? Explain
reasoning.
a. the prob. is equal
b. prob of result 1 is higher
c. prob of result 2 is higher
Two fair six sided dice are rolled.
(i) What is the probability that the smaller value of the two
results is 3 given that the sum of the two results is 8?
(ii) What is the probability that the sum of the two results is
at most 5 given that the number 2 appeared at least once?
(iii) What is the probability that the sum of the two results is
7 given that exactly one of the two results is...
Let X be the outcome of rolling a fair six-sided dice. The
possible outcomes or X are 1,2,3,4,5 and 6 and all are equally
likely. What is the cumulative distribution function F(x)?
