"To fill up the last week of the season, Larry's Paving bids on 6 similar but statistically independent small jobs. Larry has a 40% chance of getting each contract, and will net $200 on each contract he gets. Then he has to defray a $300 expense preparing the bids. a. What is the expected number of contracts he will get?

The expected number of contracts Larry will get is 2.40.

Explanation:

Let X = number of contracts Larry will get.

The probability of Larry getting a contact is, P (X) = p = 0.40

The number of bids placed is, n = 6.

Each bid is placed on statistically independent small jobs.

The random variable X follows a Binomial distribution with parameters n = 6 and p = 0.40.

The expected value of a Binomial distribution is:

Compute the expected number of contracts Larry will get as follows:

Thus, the expected number of contracts Larry will get is 2.40.

explanation:

typically a loft will include modern kitchen and bathrooms, this increases the price tag. lofts also have a good amount of open space, this requires more heating and electricity. lofts are also in older buildings, this means that maintaining the location increases the bill. keep in mind this is without talking about the high state and property taxes.
