a.
To calculate:
The expected value from each throw.
a.
Answer to Problem 3CYU
The expected value from each throw is
Explanation of Solution
Given information:
Calculation:
A game consists of trying to pop a balloon with a dart. There are
Outcome | Frequency | Probability |
Total |
To get the expected value from each dart throw, take the sum of the outcomes amd their corresponding probabilities.
Therefore, the expected value from each throw is
b.
To calculate:
The average value of the game.
b.
Answer to Problem 3CYU
The average value of the game
Explanation of Solution
Given information:
Calculation:
To simulate the balloon popping game, use a random number generator to generate integers. Use the integers
So, let
The frequency of outcomes will vary between sets of
Outcome | Frequency |
Total |
To get the frequency in the frequency table to get the observed probabilities for each outcome.
Outcome | Frequency | Probability |
Total |
To get the average value of the game, take the sum of the products of simulated outcomes and their corresponding probabilities.
Therefore, the average value of the game
c.
To explain:
The expected value and average value are compared.
c.
Answer to Problem 3CYU
The expected value and average value are very close.
Explanation of Solution
The expected value was found to be
