There are some numbers missing in your table. We think the values are supposed to be the ones shown in the attachment.
The number of people that are older than 35 and have a hemoglobin level between 9 and 11 is 46. The total number of people older than 35 is 162, so the proportion of people older than 35 with the hemoglobin level of interest is ...
... 46/162 ≈ 0.284
The appropriate choice is B. 0.284.
_____
<em>Here's how you get there with the formula for conditional probability.</em>
P(9-11 | >35) = P(9-11 & >35)/P(>35) . . . . conditional probability formula
P(9-11 | >35) = (46/429) / (162/429) = 46/162
Use form x^2 + bx + c
b = -2
c = -63
find a pair of integers whose product equals c and sum equals b
so, find a product that equals -63 and a sum that equals -2
-9 + 7 = -2
-9 • 7 = -63
write in factored form ->
(x - 9)(x + 7)
Answer:
Step-by-step explanation:
Hello!
If you consider the 6-sided dice to be balanced, then each result has the same probability of occurrence: P(1)=P(2)=P(3)=P(4)=P(5)=P(6)= 
And each time Tom rolls the dice is independent of the other times, this means that you can disregard all previous rolls and calculate the 10nth time as if it is the 1st one.
Be the event A: "Tom rolled the dice for the 10nth time and obtained a 6"
The probability of A occurring will be P(A)= 1/6
On the other hand, the complement of "A" will be 
: "Tom rolled the dice for the 10nth time and didn't obtain a 6"
This means he could obtain a 1 or a 2 or a 3 or a 4 or a 5
You can calculate the probability pf this event by adding the probability of obtaining each value P()= P(1)+P(2)+P(3)+P(4)+P(5)= 1/6*5= 5/6
Or by subtracting the probability of A to the total probability of the sample space:
P()= 1 - P(A)= 1 - 1/6= 5/6
I hope this helps!
