Going by the rules of the game to pick a random card and then multiply it by a roll of a number cube, we can find that:
- The probability a person wins a game is 3/8 or 37.5%.
- For a participant to win 25% of the time, they needs to get 32 or higher.
- The probability of a score of 36 or higher in 4 consecutive attempts is 1/1,1296.
- Teacher should tell people that just as the lower numbers could be picked, the products that are 32 or higher can be picked as well.
<h3>What sample space represents the data?</h3>
If the die is rolled, it will land on a number between 1 and 6 while there are only four cards that can be picked.
The sample space is:
Dice Card Product
1 5 5
1 6 6
1 7 7
1 8 8
2 5 10
2 6 12
2 7 14
2 8 16
3 5 15
3 6 18
3 7 21
3 8 24
4 5 20
4 6 24
4 7 28
4 8 32
5 5 25
5 6 30
5 7 35
5 8 40
6 5 30
6 6 36
6 7 42
6 8 48

Based on the products, we can come up with the following frequency table:
Frequency table
Product Frequency
5 1
6 1
7 1
8 1
10 1
12 1
14 1
16 1
15 1
18 1
21 1
24 2
20 1
28 1
30 2
32 1
25 1
35 1
40 1
36 1
42 1
<u>48 1</u>
<u>Total 24</u>
The frequency table shows that to get 28 or more, a person will have a relative frequency of:
= 1 + 2 + 1 + 1 + 1 + 1 + 1 + 1
= 9
Probability is:
= 9 / 24
= 3/8
= 37.5%
<h3>How can a person win only 25% of the time?</h3>
The number of products required to win 25% of the time is:
= 25% x 24
= 6
To find the winning number, count down from the highest product 6 times to get 32.
<h3 /><h3>What is the probability that a player wins a large prize?</h3>
The probability of getting 36 or higher is:
= ∑(Probabability of picking 36 and above numbers)
= 1 / 24 + 1/24 + 1/24 + 1/24
= 1 / 6
The probability of repeating this 4 consecutive times is:
= 1 / 6 x 1 / 6 x 1/ 6 x 1 / 6
= 1 / 1,296
= 0.0007716
