Step-by-step explanation:
a) 7!
If there are no restrictions, answer is 7! as it is the permutation of all animals.
b) 4! x 3!
As cats are 6 and Dogs are 5, thus 1st and last must be cats in order to have alternate arrangements. Therefore the only choices are the order of the cats among themselves and the order of the dogs among themselves. There
are 4! permutations of the cats and 3! permutations of the dogs,
so there are a total of 4! x 3! possible arrangements of the suites.
c) 3! x 5!
There are 3! possible arrangements of the dogs among themselves. Now, if we consider the dogs as one ”object” together, then we can think of arranging the 4 cats together with this 1 additional object. There are 5! such arrangements possible, so there are a total of 3! · 5! possible arrangements of the suites.
d) 2 x 4! x 3!
As required that all the cats must be together and all the dogs must be together, either the cats are all before the dogs or the dogs are all before the cats. There are two possible arrangements thus two times of both possibilities is the answer i.e. 2 x 4! x 3!
Answer:
umm I cant show how to graph it but the numbers are 3 pounds of blueberries so 12$ + 3 pounds of strawberry so 9$
12+9=21
Step-by-step explanation:
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
