Question

Pedro decides to roll two dice (a trial) until both dice show the same number.

What is the probability that it will take Pedro exactly 4 trials until both dice show the same number?

Answer #1

Geometric distribution

Two
dice are trown. What is the probability that the same number
appears on both dice?

If you roll two fair dice, what is the probability that the
total number of dots (or "pips") showing on the two dice is less
than 6?
A. 0.417
B. 0.278
C. 0.50
D. 0.167

You roll a pair of fair dice repeatedly. Let X denote the number
of rolls until you get two consecutive sums of 8(roll two 8 in a
row). Find E[X]

I am going to roll two fair dice.
List the sample space
What is the probability that I will roll a 3 on one of them
when I roll both at the same time?
What is the probability that I will roll at
least a sum of 7 when I roll them both?
Define mutually exclusive
Define independent

Answer the following two questions.
1. If you roll two dice, what is the probability of not getting
a sum of 7?
2. If you roll two dice, what is the probability the sum is a 4,
7, or 10?

two
dice are tossed; what is the probability that the numbers are the
same on both dice if it is known that the sum of the spots is
6

Suppose that you roll two dice. What is the probability that the
two dice are equal or differ by at most one?

You roll two fair six-sided dice. What is the probability that
the sum of the two dice values is exactly five? Be sure to count
all possible outcomes. (Hint: The event space has 36 distinct
outcomes).

We roll three fair six-sided dice.
(a) What is the probability that at least two of the dice land on a
number greater than 4?
(b) What is the probability that we roll a sum of at least
15?
(c) Now we roll three fair dice n times. How large need n be in
order to guarantee a better
than 50% chance of rolling a sum of at least 15, at least once?

Suppose that we roll a pair of (6 sided) dice until the first
sum value appears that is 7 or less, and then we stop
afterwards.
a. What is the probability that exactly three
(pairs of) rolls are required?
b. What is the probability that at least three
(pairs of) rolls are needed?
c. What is the probability that, on the last
rolled pair, we get a result of exactly 7?
