John is interested in purchasing a multi-office building containing five offices. 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 offices 0 1 2 3 4 5 probability 5/18 1/4 1/9 1/18 2/9 1/12 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? (in dollars)
a) e(x) = $23,353.33
b) e(x) = $23,333.33
c) e(x) = $23,273.33
d) e(x) = $23,263.33
e) e(x) = $23,423.33
f) none of the above.

Option B.

Step-by-step explanation:

The given table is:

Number of Lease Offices :  0           1         2       3        4         5

Probability                         : 5/18     1/4     1/9    1/18     2/9      1/12

The expected probability is

Expected probability =

Expected probability =

Expected probability =

It is given that the yearly lease = $12,000.

The yearly leases for the whole building in a given year is

Yearly leases =

Therefore, the correct option is B.

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
