Answer:
first one
Step-by-step explanation:
the sum of (9k-4) =3542
so it will be the first one because
28((5+248)/2)=3542
ANSWER;

EXPLANATIONS;
Here, we want to get the probability of A, given B; where A refers to the event that the person surveyed is under 40, and B is the event that he or she gets the news by reading news paper
According to Bayes' theorem, we have the formula to use as;

Since the total is the same, we can work only with the numbers
So, firstly, we need the number of people that gets the news by reading news papers; we have this as 28
Now, we need the number of people who are under 40 and also gets their news by reading papers
We have this as 4
So, we have the probability as;

We have this as approximately 14%
The value of a would have to be 2 in order for two sides to be equal with the coefficient of 14 and then distributing 2 would get you +6 which makes b = 6
Answer:
1/6
Step-by-step explanation:
It is a 6 sided die, so you have 6 possibilities, so that is going to be you denominator.
There is only one number 2 on the die, so you have 1 as your numerator.
