Answer:
$1,916.2
Explanation:
A fix Payment for a specified period of time is called annuity. The discounting of these payment on a specified rate is known as present value of annuity. In this question the payment of $95 per month for 24 months at APR of 16% is an annuity.
Formula for Present value of annuity is as follow
PV of annuity = P x [ ( 1- ( 1+ r )^-n ) / r ]
Where P = Annual payment = $95
First, Calculate the effective rate
EAR = ( 1 + 16%/12 )^12 - 1 = 17.2%
r = rate of return = 17.2% annual = 17.2% / 12 = 1.44% per month
n = number of years = 24 months
Placing value in the Formula
PV of annuity = $95 x [ ( 1- ( 1+ 1.44% )^-24 ) / 1.44% ]
PV of Annuity = $1,916.2
Explanation:
The interest = PTR/100
So, here P = Principcal
T = time
R = Rate of interest
= 14000 x 6 x 1 / 100 = 840
So interest = 840
So, The amount at the end = Principcal + Interest
= 14000 + 840 = 14840

Answer:
The probability that a person selected at random has virus and is aged between 21 and 25 is 0.58.
Explanation:
let A be the event that the selected person has a virus.
let B1, B2 and B3 be the events that the selected perosn is M, W and L accordingly.
the probabilities are given by:
P(B1) = 0.3
P(B2) = 0.5
P(B3) = 0.2
P(A|B1) = 0.65
P(A|B2) = 0.82
P(A|B3) = 0.5
probability of having virus and aged between 21 and 25 is given by:
[P(B2)*P(A|B2)]/[P(B1)*P(A|B1) + P(B2)*P(A|B2) + P(B3)*P(A|B3)]
= [(0.5)*(0.82)]/[(0.3)*(0.65) + (0.5)*(0.82) + (0.2)*(0.5)]
= 0.58
Therefore, the probability that a person selected at random has virus and is aged between 21 and 25 is 0.58.
