The first person can be chosen in 4 different ways.
The second person can be chosen in 3 different ways.
The third person can be chosen in 2 ways
The last person can only be chosen in 1 way.
4 * 3 * 2 * 1
there are 24 different ways that this can be done.
There is only 1 correct order.
The answer is 1/24 ways. 1/24 = 0.04166666
1 dozen eggs = 12 eggs
1.35 / 12 = 0.1125.....so the unit cost = $ 0.11 (11 cents) per egg

x=20
Step-by-step explanation:
Answer:
a.
Probability of Diet Cola = 19/28
Probability of Lemonade = 4/28
Probability of Root Beer = 5/28
b. Theoretical Probability
Step-by-step explanation:
Given
Diet Cola = 19
Lemonade = 4
Root Beer = 5
Required
Probability the her next drink will be
- Diet Cola
- Lemonade
- Root beer
To calculate the probability of each of the above, first we need to calculate the total number of drinks she's had
Total = Diet Cola + Lemonade + Root Beer
Total = 19 + 4 + 5
Total = 28
The probability that her next drink can be any of the above can then be calculated.
This is calculated by dividing each outcome by the total; as follows;
Probability of Diet Cola = 19/28
Probability of Lemonade = 4/28
Probability of Root Beer = 5/28
This type of probability is referred to as theoretical probability because it makes predictions base on previous occurrence of events.
