Alyssa and Gabriel play the following game. Alyssa rolls a die. If she rolls a 1, 2, or 3, Gabriel gives Alyssa
$5.
If Alyssa rolls a 4 or 5, Gabriel gives Alyssa
$4.
However, if Alyssa rolls a 6, she gives Gabriel
$24.
a) Determine Alyssa's expectation.
b) Determine Gabriel's expectation.
Probability of getting {1,2 or 3}=3/6
Probability of getting {4 or 5}=2/6
Probabilityof getting 6= 1/6
Now,
Que#a) Determine Alyssa's expectation.
Solutions:
Expectation (X)=$5*prob{1,2,3}+ $4*prob(4, 5) -$24* prob(x=6)
= 5*3/6+4*2/6-24*1/6=-$1/6
Ans= -$1/6. (loss)
Que(b)
b) Determine Gabriel's expectation.
Solutions:
Gabriel Expectation
= - (Alyssa's expectation
=$1/6. (,profit)
Ans=$1/6
Thanks!

2. A player pays $3 to play the following game: He rolls a die and receives $7 if he tosses a 6 and $1 for anything else. Find the player's expected net winnings for the game. What is the standard deviation?
15. Your friend challenges you to a game. She says that she is going to roll 2 6-sided dice. If the first die rolls at least 5, you win if the second die rolls less than 5. If the first die rolls less than 5, you win if the second die rolls at least 5. This seems fair. Is it? (a) What is the probability that you win this game? To incentivize you, your friend says that she will pay...

Suppose a person offers to play a game with you. You pay $1 to play the game and a person rolls a fair die with the following choices: if the die lands facing up 1 or 2. you pay $1 one more dollar if the die lands facing up 3 or 4, you only lose your initial $1 dollar; and if the die lands facing up 5 or 6 you win $3 dollars. What is your expected gain...
Your friend provides a die to play some craps on your stoop. She claims it is fair. You check and it does have sides labeled 1 to 6.

In a game of repeated die rolls, a player is allowed to roll a
standard die up to n times, where n is determined prior to the
start of the game. On any roll except the last, the player may
choose to either keep that roll as their final score, or continue
rolling in hopes of a higher roll later on. If the player rolls all
n times, then after the nth roll, the player must keep that roll
as...
Kelly is playing a dice game. She suspects her opponent of using a loaded die. While the opponent is on a snack break, Kelly grabs the die and rolls it 100 times. There were 12 1’s, 15 2’s, 13 3’s, 18 4’s, 20 5’s, and 22 6’s. At 5% significance, does Kelly have enough evidence to show that her opponent’s die is loaded?
for a game you pay 2$ to play and roll 1 die. If the number is a 1 or 2 you win 9$. If the number is a 6, you win 3$. If the number is anything else, you receive nothing. FInd the expected value (the fair price to charge to play).
