The winners of a carnival game draw a ticket from a box to determine their prize. Each winner draws a ticket and places it back into the box before the next draw. Every winner has a [tex]$57\%$[/tex] chance of getting a stuffed animal, a [tex]$17\%$[/tex] chance of getting a hat, and a [tex]$26\%$[/tex] chance of getting a keychain.

The game operator wants to simulate what could happen for the next ten winners. For each winner, he generates a random whole number from 1 to 100.

(a) What is the range of values that the game operator can use to represent a winner getting a stuffed animal?
[tex]\[ \square \text{ to } \square \][/tex]

(b) Here is the game operator's simulation.
[tex]\[
\begin{tabular}{|l|c|c|c|c|c|c|c|c|c|c|}
\hline
Winner & 1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9 & 10 \\
\hline
Random number & 41 & 58 & 4 & 23 & 72 & 1 & 5 & 47 & 44 & 52 \\
\hline
\end{tabular}
\][/tex]

Using your answer in part (a), find the percentage of the 10 simulated winners who got a stuffed animal.
[tex]\[ \square \% \][/tex]



Answer :

Let's break down and solve each part of the problem step-by-step.

### Part (a)
Question:
What is a range of values that the game operator can use to represent a winner getting a stuffed animal?

Solution:
A winner has a 57% chance of getting a stuffed animal. To simulate this using random numbers from 1 to 100, we assign the first 57 numbers (1 to 57) to getting a stuffed animal.

Thus, the range of values representing a winner getting a stuffed animal is from:
[tex]\[1 \text{ to } 57\][/tex]

### Part (b)
Question:
Given the random numbers drawn by the winners, find the percentage of the 10 simulated winners who got a stuffed animal.

Solution:
To determine how many winners got a stuffed animal, we look at the random numbers and see if they fall within the range 1 to 57.

Here are the random numbers drawn by each winner:
[tex]\[41, 58, 4, 23, 72, 1, 5, 47, 44, 52\][/tex]

We count how many of these numbers are within the range 1 to 57:
- 41 is within 1 to 57
- 58 is not within 1 to 57
- 4 is within 1 to 57
- 23 is within 1 to 57
- 72 is not within 1 to 57
- 1 is within 1 to 57
- 5 is within 1 to 57
- 47 is within 1 to 57
- 44 is within 1 to 57
- 52 is within 1 to 57

Counting the qualifying numbers, we find there are 8 winners who got a stuffed animal.

To find the percentage of winners who got a stuffed animal:
[tex]\[ \text{Percentage} = \left( \frac{\text{Number of winners who got stuffed animals}}{\text{Total number of winners}} \right) \times 100 \][/tex]
[tex]\[ \text{Percentage} = \left( \frac{8}{10} \right) \times 100 = 80\% \][/tex]

Thus, the percentage of the 10 simulated winners who got a stuffed animal is:
[tex]\[80\% \][/tex]

### Summary:
(a) Range of values representing a winner getting a stuffed animal:
[tex]\[1 \text{ to } 57\][/tex]

(b) Percentage of the 10 simulated winners who got a stuffed animal:
[tex]\[80\% \][/tex]
