A salesman goes house to house in a local location to show the utilization of another home device to likely clients. Toward the finish of a demonstration,the likelihood that the potential client would put in a request for the item is aconstant 0.2107. To perform sufficiently at work, the salesman needs at leastfour orders. Expect that every exhibit is a Bernoulli preliminary.

\17\

a. On the off chance that the salesman needs to be in any event 90% certain of getting at any rate

4 orders, at any rate what number of shows would it be advisable for her to make?

b.The salesman has the opportunity to make just 22 exhibitions, she still

needs to be in any event 90% sure of getting at any rate 4 orders. She means

to acquire this certainty by improving the nature of her exhibit and

subsequently improving the odds of getting a request toward the finish of a showing. In any event to what exactly esteem should this likelihood be expanded inorder to acquire the ideal certainty? Your answer ought to be precise to

four decimal spots.

Jamal Crawford of the National Basketball Association's Portland Trail Blazers is the best free-toss shooter in the group, making 93% of his shots (ESPN site, April 5, 2012). Expect that late in a b-ball game, Jamal Crawford is fouled and is granted two shots.

a. What is the likelihood that he will make the two shots?

b. What is the likelihood that he will make in any event one shot?

c. What is the likelihood that he will miss the two shots?

What is the likelihood an individual enormous cap homegrown stock asset had a three-year return of at any rate 20%? b. What is the likelihood an individual huge cap homegrown stock asset had a three-year return of 10% or less? c. How large does the return need to be to placed a homegrown stock asset in the top 10% for the three-year time frame?
