Question

what is p, the probability of success? what is 1 - p, the probability of failure?

Explanation:

Step1: Calculate probability of success

The total number of sections is \(1 + 3=4\). The number of green (success) sections is 1. So the probability of success \(p=\frac{\text{Number of successful outcomes}}{\text{Total number of outcomes}}=\frac{1}{4}\).

Step2: Calculate probability of failure

The probability of failure is \(1 - p\). Since \(p = \frac{1}{4}\), then \(1-p=1-\frac{1}{4}=\frac{3}{4}\).

Answer:

The probability of success \(p=\frac{1}{4}\), the probability of failure \(1 - p=\frac{3}{4}\)
