Answer:
$46844.94
Step-by-step explanation:
First, find number of years between 2022 and 2018
2022-2018 = 4
Turn 6% into a decimal: .06
Use exponential decay formula:
original number(1-decay percentage)^number of years
60000(1-.06)^4 = 46844.9376
Using the given equation:
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = 1/6 + 5/12 - ( 1/6 * 5/12)
P(A or B) = 7/12 - 5/72
P(A or B) = 37/72
A.
