To solve this, we take the number of subjects who weren't diabetic, and then divide them by the total number of subjects who took the test:
Probability =
=
= 0.903225..
= 0.90 (rounded)
-------------------------------------------------------------------------------------------------------------
Answer:
So the probability of randomly selecting a subject who was not diabetic would be <u></u>0.90 (the final option)
-------------------------------------------------------------------------------------------------------------
<em>Note:
</em> <em>We only used the numbers under 'Negative Test', because the question wanted the probability 'given that the test result was negative'</em>

Answer:
The value of b is, 8
Step-by-step explanation:
To determine the value of b:
Given:
....[1]
Since, 0x6A represents the hexadecimal form.
To convert this hexadecimal form into decimal form:
⇒(decimal form)
Now we have to convert this decimal form into octal
8 | 106
8 | 13 | 2
| 1 | 5
1
Then, the octal form we get,
Substitute this in [1] we have;
On comparing both sides we have;
b = 8
Therefore, the value of b is, 8
Answer:
15 is the total number of animals for which (p ∨ q) ∧ r true.
Step-by-step explanation:
From the diagram it is clear that
p contains {2, 5, 8, 9}
q contains {2, 4, 7, 5}
r contains {2, 4, 6, 9}
p ∨ q is the union of p and q which include all the animals which are in p, in q, or in both p and q.
Note: p ∨ q can not have duplicate animals
So,
p ∨ q = {2, 4, 5, 7, 8, 9}
(p ∨ q) ∧ r contains the animals which need to be common in both (p ∨ q) and r.
As
p ∨ q = {2, 4, 5, 7, 8, 9}
r = {2, 4, 6, 9}
So,
(p ∨ q) ∧ r = {2, 4, 9}
As
Therefore, 15 is the total number of animals for which (p ∨ q) ∧ r true.
