Question

1. predicting the probability that a negative outcome, such as equipment failure, will occur is an important part of risk analysis. given the following scenario, what is the probability of a negative outcome? students designed and developed a robotic arm which automatically loaded plastic resin into an injection mold. the students conducted 20 performance tests and the robotic arm malfunctioned once. 0.05 0.02 0.01 0.2

Explanation:

Step1: Recall probability formula

Probability = $\frac{\text{Number of negative outcomes}}{\text{Total number of tests}}$

Step2: Identify values

Number of negative outcomes = 1, Total number of tests = 20

Step3: Calculate probability

Probability = $\frac{1}{20}= 0.05$

Answer:

0.05
