You are developing a system to predict the prices of insurance for drivers in the United Kingdom. You need to minimize bias in the system. What should you do?

• Remove information about protected characteristics from the data before sampling.

• Take a training sample that is representative of the population in the United Kingdom.

• Create a training dataset that uses data from global insurers.

• Take a completely random training sample.

Azure Machine Learning designer lets you create machine learning models by ​ (a)  

• adding & connecting modules on visual canvas
• performing common data preparation task
• selecting algorithm to build most accurate model
• using code-first notebook experience
