The statement of the problem is
Kevin’s family has a history of diabetes. The probability that Kevin would inherit this disease is 0.75. Kevin decides to take a test to check if he has the disease. The accuracy of this test is 0.85
Probability
Test predicts he has it 0.85
Test predicts he doesn’t have it 0.15
Kevin has diabetes 0.75
<span>Kevin doesn’t have diabetes 0.25
</span>
Answers
<span>1) </span>The
probability that Kevin has diabetes and the test predicts he has diabetes
P=0.75*0.85=0.6375
<span>2) </span>The
probability that Kevin has diabetes and the test predicts the opposite to the
true
P=0.75*0.15=0.1125
<span>3) </span>The
probability that Kevin not have diabetes and the test predicts it correctly
P=0.25*0.85=0.2125
<span>4) </span>The
probability that Kevin not have diabetes and the test predicts he has diabetes
P=0.25*0.15=0.0375
Answer:
4/8, simplified as 1/2
Step-by-step explanation:
Answer:
9 textbooks!
Step-by-step explanation:
Rucksack can hold = 6kg
Mass of textbook = 680g
So, here we need to show the division for finding the number of textbooks it can hold.
680 g in KG's = 0.68
Now, 6/0.68
That is 8.82 ( Round off = 9 textbooks)
Answer:
x=-10
Step-by-step explanation:
you have to first get x on one side so subtract 2x.
x+2=-8
then you have to isolate x, so subtract 2
x=-10
and that's your answer, hope this helped!
