Answer:
1) His total commission is $1,234.3
2) The purchase of the car is $24,790.
Step-by-step explanation:
1) 21640*0.02= 432.8+ 250= 682.8
15075*0.02= 301.5+ 250= 551.5
682.8+ 551.5= 1,234.3
2) 745.8- 250= 495.8/ 0.02= 24,790
So,
The probability of the man having diabetes is 0.6 or 60%. Because we are figuring the probability BEFORE the test is taken that he has the disease, we can disregard the test and its accuracy rate. That rate is 60%, the probability of him having diabetes.
The correct option is D.
