Business and Management Two packages are independently shipped from Fort Collins, Colorado, to the Convention Center in Kansas City, Missouri, and each is guaranteed to arrive within four days. The probability that a package arrives within one day is 0.10, within two days is 0.15, within three days is 0.25, and on the fourth day is 0.50.
Let the random variable X be the total number of days for both packages to arrive. Construct the probability distribution for X.
