### Probability and Odds in Education

**4. A student is randomly chosen. Find P(L ∩ H) and P((L ∩ H)') and explain what each number represents.**

**d.**
1. **P(L ∩ H) =** ``

**Explain what P(L ∩ H) and P((L ∩ H)') represent. Choose the correct answer below.**

- [ ] A. P(L ∩ H) is the probability a student is taking a lab science and is a member of the Honors College. P((L ∩ H)') is the probability a student is not taking a lab science or is not a member of the Honors College.
- [ ] B. P(L ∩ H) is the probability a student is taking a lab science or is a member of the Honors College. P((L ∩ H)') is the probability a student is not taking a lab science or is not a member of the Honors College.
- [ ] C. P(L ∩ H) is the probability a student is taking a lab science or is a member of the Honors College. P((L ∩ H)') is the probability a student is not taking a lab science and is not a member of the Honors College.
- [ ] D. P(L ∩ H) is the probability a student is taking a lab science and is a member of the Honors College. P((L ∩ H)') is the probability a student is not taking a lab science and is not a member of the Honors College.

**e. Find the odds against each event in parts (d-e) occurring.**

**First, write an expression for the odds against H. Select all that apply.**

- [ ] A. P(H'): P(H)
- [ ] B. P(H): (1 - P(H'))
- [ ] C. P(H): (1 - P(L))
- [ ] D. 1 - P(H): P(H)
- [ ] E. (1 - P(H)): P(H')
- [ ] F. P(H): P(H')

**The odds against H occurring, in lowest terms, are:** `__ : __`
- *(Type whole numbers.)*

### Understanding Probability with Venn Diagrams

A poll of 220 students at a university reveals that 90 are taking a lab science course, and 55 are members of the Honors College, while 18 are taking a lab science and are members of the Honors College. Let \( L \) be the event that a student is taking a lab science, and \( H \) be the event that a student is a member of the Honors College. Complete parts (a) through (c) below.

#### a. Display this data in a Venn diagram. Choose the correct diagram below.

- **Option A:**
  - Lab Science (L): 72
  - Overlap (L and H): 18
  - Honors College (H): 37
  - Outside Both Sets: 93

- **Option B:**
  - Lab Science (L): 90
  - Overlap (L and H): 18
  - Honors College (H): 55
  - Outside Both Sets: 103

- **Option C:**
  - Lab Science (L): 72
  - Overlap (L and H): 18
  - Honors College (H): 37
  - Outside Both Sets: 135

- **Option D:**
  - Lab Science (L): 52
  - Overlap (L and H): 18
  - Honors College (H): 37
  - Outside Both Sets: 113

#### Correct Answer: Option A

#### b. A student is randomly chosen. Find \( P(L) \) and \( P(L^c \cap H^c) \) and explain what each number represents.

##### First determine the formula to use to find \( P(L) \).

\[ P(L) = \frac{\text{Number of students taking a lab science}}{\text{Total number of students}} \]

\[ P(L) = \frac{90}{220} \]

\[ P(L) (Simplify your answer) \]

##### Determine the formula to use to find \( P(L^c \cap H^c) \).

\[ P(L^c \cap H^c) = \frac{\text{Number of students not taking a lab science and not in the Honors College}}{\text{Total number of students}} \]

\[ P(L^c \cap H^c) = \frac{93
