The current owner provides the following probability distribution indicating the probability that the given number of offices will be leased each year. Number of Lease Offices012345 Probability5/323/163/321/49/321/32 If each yearly lease is $12,000, how much could John expect to collect in yearly leases for the whole building in a given year

$28,875

Step-by-step explanation:

The given table is:

The expected probability is derived using the formula:

Therefore, for the given distribution,

Expected Probability

If each yearly lease is $12,000

The Expected Yearly Lease for the Whole Building=2.40625 X 12000

=$28,875

the 4th choice is the correct one

step-by-step explanation:

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
