How to find the whether the question is asking present value of annuity or future value of annuity?

latest answer

For direct questions they will give in question itself. For practical questions you need to find the application of that, whether you need to find what is the today's money if invested how much it is going to get at end of certain period is future value. On contrary, if you want to know tomorrow's value of money as of today you will discount it for present along with interest. Then use formula and solve more and more problems.

If a fair die is thrown 2 times, let A and B be the events, â??same number each timeâ?? and â??a total score is 10 or more,â?? respectively. Determine whether or not the events A and B are independent. A. Mutually exclusive B. Independent C. Dependent D. None of the above Can someone give the correct ans with explanation? I am confused between options a and b

latest answer

Condition for event A= same number each time A ={(1,1),(2,2),(3,3),(4,4),(5,5),(6,6)} P(A) = 6/36 =1/6 Conditon for event B=total score is 10 or more B = {(4,6),(6,4),(5,5),(6,5),(5,6),(6,6)} P(B) = 6/36 = 1/6 conditon for event A and B= same number each time and total score is 10 or more (Aâ?©B)= {(5,5),(6,6)} P(Aâ?©B) =2/36=1/18 P(Aâ?©B) â?  P(A)+P(B) Hence, events A and B are not independent. And also not mutually exclusive[ bcz P(Aâ?©B)â?  0} So Option C is right.

Second last line, 10(10n-1)/9-n How is it equal to 10n+1 -9 When 10(10n-1) should be equal to 100n-10.

latest answer

n here is to the power of 10. So, you have 10 x 10^n = 10^(n+1). That n+1 to power of 10 And then they have taken 9 in denominator outside
