Answer:
11%
Explanation:
Compounding is the method used to determine the future worth of an amount today while discounting is the method used to determine the present value of a future amount.
Both are related by
Fv = Pv(1 + r)^n
where Fv is the future amount
Pv is the present value
r = rate
n = time
As such,
18.5 = 15 (1 + r)^2
1.2333 = (1 + r)^2
1 + r = 1.11
r = 0.11
the annual percent on returns is 11%

Answer:
a) 0.0358
b) 0.0395
c) 0.1506
Explanation:
Number of clues "daily doubles" = 3
Determine the probabilities
<u>a) P(single contestant finds all three ) </u>
assuming event A= a returning champion gets the "daily double" in first trial
P(A) = 1/30 , P(~A) = 29/30
assuming event B = any player picks up "daily double" after the first move
P(B |~A ) = 1/3
hence : P ( B and ~A ) = 29/30 * 1/3 = 29/90
<em>considering second round </em>
P(player chooses both daily doubles ) = 1/3 * 1/3 = 1/9
∴ P(single contestant finds all three ) = 29/90 * 1/9 = 0.0358
<u>B) P ( returning champion gets all three ) </u>
= (1/30 + 29/90 )* 1/9
= 32 / 810 = 0.0395
<u>c) P ( each player selects only one )</u>
P = 32/405 + 29/405
= 61 / 405 = 0.1506
