Components 1 and 2 are connected in parallel, so that their subsystem functions correctly if either component 1 or 2 functions. Components 3 and 4 are connected in series, so their subsystem works only if both components work correctly. If all components work independently of one another and P(a given component works) = .9, calculate the probability that the entire system works correctly.

### Component System Probability Analysis

**Figure Description:**

The figure illustrates a system of four components connected in a specific configuration, depicted by four labeled boxes connected by lines. The components are as follows:

- **Components 1 and 2**: These are connected in parallel. In a parallel configuration, the subsystem functions correctly if at least one of the components is working.
- **Components 3 and 4**: These are connected in series. In a series configuration, the subsystem functions only if both components are working.

**Task:**

Calculate the probability that the entire system works correctly, given:

- Each component operates independently.
- The probability of any given component working is \( P(\text{component working}) = 0.9 \).

**Solution Approach:**

1. **Parallel Configuration (Components 1 and 2):**
   - Probability that either Component 1 or 2 works:
     - \( P(\text{at least one works}) = 1 - P(\text{neither work}) \)
     - \( P(\text{neither 1 nor 2 work}) = (1 - 0.9)(1 - 0.9) = 0.1 \times 0.1 = 0.01 \)
     - \( P(\text{at least one works}) = 1 - 0.01 = 0.99 \)

2. **Series Configuration (Components 3 and 4):**
   - Probability that both Component 3 and 4 work:
     - \( P(\text{both work}) = P(\text{3 works}) \times P(\text{4 works}) = 0.9 \times 0.9 = 0.81 \)

3. **Entire System:**
   - Final probability that the entire system functions is the product of the probabilities of each subsystem functioning:
     - \( P(\text{system works}) = P(\text{1 and 2 parallel}) \times P(\text{3 and 4 series}) = 0.99 \times 0.81 = 0.8019 \)

Therefore, the probability that the entire system works correctly is **0.8019**.
