Answered

Dave, Frida, Natalie, and Robbie have four adjacent seats at a baseball park. They randomly choose an order to sit in.

1. Make a list of all the possible ways in which they can sit in the four seats.
2. Match the events to their correct probabilities.

- The probability of Dave and Natalie sitting together.
- The probability of Frida and Natalie sitting together.
- The probability of sitting boy, girl, boy, girl or girl, boy, girl, boy.
- The probability of Robbie sitting between the girls.
- The probability of the two boys sitting in the middle.
- The probability of Natalie sitting between Dave and Robbie.

Alright, let's dive into it step by step.

### Step 1: List of All Possible Ways They Can Sit

There are 4 people, and we need to find all the permutations of how they can sit in the 4 seats. The total number of permutations is calculated as [tex]\(4! = 4 \times 3 \times 2 \times 1 = 24\)[/tex].

### Step 2: Calculate Probabilities

Now let's calculate the probabilities for each event given all 24 possible permutations.

#### Probability of Dave and Natalie Sitting Together

There are 12 favorable permutations where Dave and Natalie sit together out of the 24 total permutations.

Thus, the probability is [tex]\(\frac{12}{24} = 0.5\)[/tex].

#### Probability of Frida and Natalie Sitting Together

Similarly, there are 12 favorable permutations where Frida and Natalie sit together out of the 24 total permutations.

Thus, the probability is [tex]\(\frac{12}{24} = 0.5\)[/tex].

#### Probability of Sitting Boy, Girl, Boy, Girl or Girl, Boy, Girl, Boy

There are 8 favorable permutations where the seating arrangement follows the boy, girl, boy, girl or girl, boy, girl, boy pattern out of the 24 total permutations.

Thus, the probability is [tex]\(\frac{8}{24} \approx 0.3333\)[/tex].

#### Probability of Robbie Sitting Between the Girls

There are 2 favorable permutations where Robbie sits between the girls out of the 24 total permutations.

Thus, the probability is [tex]\(\frac{2}{24} \approx 0.0833\)[/tex].

#### Probability of the Two Boys Sitting in the Middle

There are 4 favorable permutations where the two boys sit in the middle out of the 24 total permutations.

Thus, the probability is [tex]\(\frac{4}{24} \approx 0.1667\)[/tex].

#### Probability of Natalie Sitting Between Dave and Robbie

There are 2 favorable permutations where Natalie sits between Dave and Robbie out of the 24 total permutations.

Thus, the probability is [tex]\(\frac{2}{24} \approx 0.0833\)[/tex].

### Summary

Here’s the matching of events to their probabilities:

- The probability of Dave and Natalie sitting together: [tex]\(0.5\)[/tex]
- The probability of Frida and Natalie sitting together: [tex]\(0.5\)[/tex]
- The probability of sitting boy, girl, boy, girl or girl, boy, girl, boy: [tex]\(0.3333\)[/tex]
- The probability of Robbie sitting between the girls: [tex]\(0.0833\)[/tex]
- The probability of the two boys sitting in the middle: [tex]\(0.1667\)[/tex]
- The probability of Natalie sitting between Dave and Robbie: [tex]\(0.0833\)[/tex]

These probabilities provide the likelihood of each described event happening given the seating arrangements of Dave, Frida, Natalie, and Robbie.
