Question

- If you roll a die and flip a coin. What is the probability of rolling a 3 and flipping a tails?

Answer #1

You flip a fair coin. If the coin lands heads, you roll a fair
six-sided die 100 times. If the coin lands tails, you roll the die
101 times. Let X be 1 if the coin lands heads and 0 if the coin
lands tails. Let Y be the total number of times that you roll a 6.
Find P (X=1|Y =15) /P (X=0|Y =15) .

You create a game that involves flipping a coin and rolling a
six-sided die. When a player takes their turn they first flip the
coin to determine if they are going to deal or receive damage. The
person then rolls the die to determine the amount of damage dealt.
For this game, explain the difference between an event versus a
simple event. What does that have to do with sample space
Give the sample space for the game. Use H...

A game is played by first flipping a fair coin, then rolling a
die multiple times. If the coin lands heads, then die A is to be
used; if the coin lands tails, then die B is to be used. Die A has
4 red and 2 white faces, whereas die B has 2 red and 4 white faces.
If the first two throws result in red, what is the probability that
the coin landed on heads?

Please Explain!
a. You flip a coin and roll a die. Describe the sample space of
this experiment.
b. Each of the 10 people flips a coin and rolls a die. Describe
the sample space of this experiment. How many elements are in the
sample space?
c. In the experiment of part b. how many outcomes are in the
event where nobody rolled a five? How many outcomes are in the
event where at least one person rolled five?
d....

You roll a normal 6-sided die. What is the probability of
rolling at least one 5 if you roll 3 times?

QUESTION 1
You flip a coin and roll a 10 sided die. How many elements are
in the sample space?
QUESTION 2
You flip a coin and roll a 10 sided die. What is the probability
getting a tail and rolling a 5?
QUESTION 3
How many ways can you select 2 items from 20 if order does not
matter?
QUESTION 4
How many ways can you select 2 items from 20 if order
matters?
QUESTION 5
Suppose that we...

You flip a coin until getting heads. Let X be the number of coin
flips.
a. What is the probability that you flip the coin at least 8
times?
b. What is the probability that you flip the coin at least 8
times given that the first, third, and fifth flips were all
tails?
c. You flip three coins. Let X be the total number of heads. You
then roll X standard dice. Let Y be the sum of those...

You roll a six-sided die. Find the probability of each of the
following scenarios.
(a) Rolling a 6 or a number greater than 3
(b) Rolling a number less than 5 or an even number
(c) Rolling a 4 or an odd number

REPOST: A biased coin has 0.75 probability of flipping
heads and 0.25 of flipping tails. What is the probability that the
sequence TTHH (T=tails, H=heads) only occurs after the 8th
flip?

If we are rolling a six-sided die what is the probability of
rolling a 2 or 3 on the first roll and a 2, 3, or 4 on the second
roll
a. 5/36 or 0.14
b. 6/36 or 0.17
c. 6/12 or 0.50
d. 3/36 or 0.08
