Answer:
-$0.16
Step-by-step explanation:
The expected value is the sum of the outcomes multiplied by their probabilities.
E(X) = 1/38 (+68) + 37/38 (-2)
E(X) = -0.16
Answer:
-3 < x < 1, This is the domain
The number of years it will take to earn his first million is 24 years
Average bi-weekly gross pay = $1,630
Bi-weekly = 2 weeks
Number of 2 weeks(bi-weeks) in a year = 26 bi-weeks
The least million he can earn is $1,000,000
Let the number of years = n
We could use the equation :
Least million = gross pay × (Number of bi-weeks × number of years)
1000000 = 1630 × (26n)
1000000 = 42380
Divide both sides by 34230
1000000 / 42380 = n
n = 23.59
The least number of years is 24.
