Amarillo Slim, a professional dart player, has an 80% chance of hitting the bull's eye on a dartboard with any throw. Assume each throw at the dartboard is independent of any other throw.
Suppose, now that Amarillo Slim throws 10 darts, one at a time, at the dartboard. What is the probability he gets exactly 7 bull's eyes? (to 4 decimals)
Homework Answers
Solution
Given that ,
p = 0.80
q = 1 - p = 1 - 0.80 = 0.20
n = 10
Using binomial probability formula ,
P(X = x) = (n C x) * p x * (1 - p)n - x
P(X = 7) = (10 C 7) * 0.80 7 * (0.20)10 - 7
Probability =0.2013

A dart player throws 10 darts at the dart board. He has a 20% chance of hitting the bull’s eye each time. Suppose throws are independent. What is the probability that he hits the bull’s eye 4 times? What is the probability that he hits the bull’s eye at least twice? How many times would he be expected to hit the bull’s eye? What is the standard deviation of the number of times he is likely to hit the bulls...

Suppose we have a really good dart player and in each throw, suppose the probability of hitting the bulls eye is 0.4. If the player throws 4 darts, what is the expected number of darts that hit the bulls eye?

9, (2 marks) (from P. 33 #77) A player throws darts at a target. On each trial, independently of the other trials, he hits the bull's-eye with probability 04. What is the fewest number of throws so so that his probability of hitting the bull's-eye at least once is more than5?

1. Bull's-Eye Bonanza. (Allotted Time 45 minutes) Suppose you want to throw a dart across a room at a wall-mounted target and hit the target exactly at its center point. We call this center point of the target its "bull's eye". The bull's-eye is a horizontal distance d from the dart's point of release and a height h above the dart's point of release. To hit the bul'seye, you have a choice of the speed s at which you throw...

Suppose a basketball player is an excellent free throw (shots awarded when a player is fouled) shooter and makes 80% of his free throws (or he has and 80% chance of making a single free throw). Assume that free throw shots are independent of one another. Suppose this player gets to shoot four free throws. Find the probability that he makes four consecutive free throws.
Suppose you have a friend on the school basketball team but, unfortunately, he is not a good free throw shooter. Over the course of his career, he has only made 40% of his shots. Otherwise, he is a go...
Suppose you have a friend on the school basketball team but, unfortunately, he is not a good free throw shooter. Over the course of his career, he has only made 40% of his shots. Otherwise, he is a good player and gets fouled a lot so he shoots 10 free throws a game, on average. In the biggest game of the season, he does very well and makes 6 out of 10 free throw attempts. ? A. Assuming that each...

1. Rhoda Ruyner owns a $200,000 home and has a 2% chance of experiencing a loss that destroys her home in any given year. Assume that only one loss per year can occur and that if a loss occurs, her home is totally destroyed. Suppose that Rhoda purchases a full insurance contract from Acme Insurance for an actuarially fair premium. This contract would pay losses due to the total destruction of Rhoda’s home. Assume that Rhoda’s contract is the only...

The Binomial and Poisson Distributions Both the Binomial and Poisson Distributions deal with discrete data where we are counting the number of occurrences of an event. However, they are very different distributions. This problem will help you be able to recognize a random variable that belongs to the Binomial Distribution, the Poisson Distribution or neither. Characteristics of a Binomial Distribution Characteristics of a Poisson Distribution The Binomial random variable is the count of the number of success in n trials: number of...
