In a board game, each player takes turns pressing a "popper" that contains a single die. To begin moving a game piece around the board a player must first pop a 4 or a 6 on the die. The number of tries required toget a 4 or a 6 can be described by the geometric distribution, for which the probability for success after x tries is given by f(x) = (1- p)X-1p, x= 1,2,3,.., where p is the probability of success on a given try. Note that1Complete parts a. and b. below.the expected value for f isa. Using the expected value for f, what is the expected number of times a popper must be pressed before a success occurs?(Simplify your answer.)

Let p be the probability of getting a 4 or 6. It is known that the possible outcomes for rolling a…

Mendelian Genetics When Mendel conducted his famous genetics experiments with peas, one sample of offspring consisted of 428 green peas and 152 yellow peas. Based on chose results, estimate the probability of getting an offspring pea that is green. Is the result reasonably close to the expected value of 3/4, as claimed by Mendel?

Suppose a life insurance company sells a $210,000 1-year term life insurance policy to a 20-year-old female for $290. According to the National Vital Statistics Report, 58(21), the probability that the female survives the year is 0.999544. Compute and interpret the expected value of this policy to the insurance company. The expected value is $ (Round to the nearest cent as needed.)

The useful life of Johnson rods for use in a particular vehicle follows an exponential distribution with an average useful life of 5.2 years.You have a three-year warranty on your vehicle’s Johnson rod. What is the probability that the Johnson rod doesn’t fail before then? That is, what is the probability that its useful life doesn’t end before three years?b.If the vehicle manufacturer wants to limit the number of claims on the three-year warranty to 20%, what should the average useful life of the Johnson rod be?
A food truck near the University of Windsor specializes in healthy sandwiches. The sandwiches are prepared fresh each morning and any unsold sandwiches are donated to a food bank. Each sandwich costs $6 to make and sells for $10. The daily number of sandwiches sold, x, has the following distribution: (shown in image) a. Fill in the missing probability in the table above b. What is the expected daily profit? (hint: find the mean of x and multiply it by profit per sandwich) c. Find the mean, variance and standard deviation of the number of daily number of sandwiches sold. d. What is P(x  2| x < 4)?
