The rate at which attempts to obtain a desired material are successful is called the?

• A. Yield
• B. Efficiency
• C. Strike rate
• D. Probability

Answer: (C)

This is about how often attempts to obtain a desired material succeed, i.e., the rate of successful outcomes per try. The term that fits this idea best is strike rate, because it measures the actual proportion of successes across multiple attempts. You calculate it by dividing the number of successful outcomes by the total number of attempts, then usually express as a fraction or percentage (for example, if you succeed 8 times in 50 attempts, the strike rate is 8/50 = 0.16 or 16%). Yield is about how much material you get from a given amount of starting material, not how often attempts succeed. Efficiency compares useful output to total input, not the frequency of successful attempts. Probability is the theoretical chance of success on a single attempt, not the observed rate over many attempts.
