b. What is the probability that the customer is not a poor risk?
ANSWER:
Answer:
Step 1 of 2:
(a)
In this question, we are asked to find the probability that the customer is a good risk.
Given data:
of customers are good risks.
of customers are medium risks.
of customers are poor risks.
Since given data is in percentage.
We can say out of 100, 70 customers are good risks.
Hence our probability would be
=
=
= 0.7
Hence the probability that the customer is a good risk is 0.70.
