Assume 8 dollar bills are randomly selected. Find the probability that at least 5 of them have traces of cocainePlease answer all parts. Thank you!A local county has an unemployment rate of 6.1%. A random sample of 20 employable people are picked at random from the county and are asked if they are employed. The distribution is a binomial. Round answers to 4 decimal places. Find the probability that there are at most 2 in the sample are unemployed.
- A professional basketball player has an 81% success rate when shooting free throws. Let the random variable X represent the number of free throws he makes in a random sample of 10 free throws (assume this experiment meets all binomial requirements). What is the probability that he makes exactly 7 of the 10 free throws? Note: You do not need to solve for the exact probability; you just need to choose the equation below that correctly represents how you would solve for this probability. 10! -(0.81)7(0.19)10 3!7! P(X=7) a. 10! P(X=7) = (0.81)7(0.19)³ O b. 7! 10! P(X=7) = (0.81)7(0.19)3 C. 3! P(X=7) = d. 10! -(0.81)3(0.19)7 3!7! 7! P(X=7) = 3! -(0.81) (0.19)7 е.

If he takes 50 shots, find: a) the probability he makes at most 30 using the normal approximation to the binomial. b) the probability he makes exactly 28 using the normal approximation to the binomial.When X is a binomial random variable, the mean of the probability distribution = np. A jury has 12 people on the jury. If a certain town has a population that is 9 percent a certain race, how many people of that race would you expect would be on the jury if jury selection was random (and every person was equally likely to be on the jury). Round answers to 4 decimal places as needed.

You ramdomly select 50 people.use normal approximation to find the probability that at least 35people will go to the restaurant. Solve it by binomial.A large bag contains pretzels with 3 different shapes: heart, square, circle . Billy plans to reach into the bag and draw out one pretzel at a time, stopping only when he has at least one pretzel of each type. Let the random variable X denote the number of pretzels that Billy will draw from the bag. You can assume that there is an infinite number of pretzels in the bag with equal proportions of each shape. Find E(X).
