Answer:
D) Of the 4 people who have a sister, 1 of them also has a brother.
Step-by-step explanation:
P(B/A) indicates the probability of event B when event A has alredy occured.
Event A = The person has a sister.
Event B = The person has a brother.
So now P(B/A) means the probability of the person having sister who already have brother.
Hence choice "D) Of the 4 people who have a sister, 1 of them also has a brother." is correct.

Each of the answers given at the right talks about the fourth month. So let's compare each of the fourth month's profits.
When the month t = 4 in Company B, the company made 10 hundred (or 1000) dollars in profits.
When the month t = 4 in Company A, we evaluate the function at t = 4. To do that we put t = 4 into the function.
P(4) = 1.8(1.4)⁴
P(4) = 6.91488
Thus the company made 691.488 dollars of profit. So during the 4th month, Company B made more than A.
Each of the answers also talks about year end profits, which would be after 12 months. The function for company B is linear whereas it is exponential for A. An exponential function will grow faster in A and have higher maximum values. We can conclude that year end profits for A will be higher.
We put the statements together - that B makes in the 4th month but at year's end A will make more.
Thus, the third box is the best answer.

Step-by-step explanation:
The formula for a geometric sequence is where is the th term of the sequence, is the first term, and is the common ratio.
Since each term is being multiplied by 3, this is our common ratio.
Therefore, our geometric sequence formula is
