A. What are the assumptions of a binomial distribution? Does the example match the assumptions?

B. What is the probability that the sample has exactly n successes, for n=1,2,3…10?

C. Plot the probabilities that were calculated in B.

D. Find the probability that the sample has at least 5 successes.

Short circuit evaluation is when the language evaluates the first portion of a BOOLEAN expression and if, knowing the result of the value, then skips the evaluation of the second expression. For example, A & B is false if A is false... no need to evaluate B. A similar scenario is true for OR. Most languages implement short circuit evaluation

create a program for the following languages: FORTRAN

Write the summary of your result

An example could look like:

function f()

{ write('I have been evaluated');
      return(1);

}

main()
{   int i=1;

if ( i ==0 && f() )
then write ('true')
else   write ('false)

John, Lesa, and Trevor form a limited liability company. John contributes 60 percent of the capital, and Lesa and Trevor each contribute 20 percent. Nothing is decided about how profits will be divided. John assumes that he will be entitled to 60 percent of the profits, in accordance with his contribution.

Mark is also interested in reducing the cost of selling of his Christian Dior shares, Ali suggested that he should use European electronic crossing network to sell some of his shares. He told Mark that these networks are cheap, preserve anonymity and allows for 6 crossing opportunities of trades per day. They also allow participants to place some restrictions such as price and minimum fill. All orders submitted to the network is good for day which is means that any unfulfilled part of an order is automatically resubmitted to subsequent crossing sessions during the day. Following Ali’s advice, Mark has submitted his 150,000 CD shares to be sold in the European crossing network with a minimum fill of 125,000. The following orders are on the network for the shares of CD at the time of the first crossing session of the day. The most recent trading price of CD at the Paris Bourse is € 37.

A order: a market order to buy 100,000 shares

B order: a market order to sell 50,000 shares

C: an order to buy 20,000 shares at € 36

In the next crossing session new orders are submitted. The most recent trading price of CD at the Paris Bourse is € 38.

D order: a market order to buy 150,000 shares

E order: A market order to sell 50,000
