"Multinomial Experiments In Exercises 39 and 40, use the information below.
A multinomial experiment satisfies these conditions.
The experiment has a fixed number of trials n, where each trial is independent of the other trials.
Each trial has k possible mutually exclusive outcomes:
Each outcome has a fixed probability. So, . The sum of the probabilities for all outcomes is
The number of times occurs is , the number of times occurs is , the number of times occurs is , and so on.
The discrete random variable x counts the number of times that each outcome occurs in n independent trials where . The probability that x will occur is
Genetics Another proposed theory in genetics gives the corresponding probabilities for the four types of plants described in Exercise 39 as , and . Ten plants are selected. Find the probability that 5 will be tall and colorful, 2 will be tall and colorless, 2 will be short and colorful, and 1 will be short and colorless."

Mega Millions In Mega Millions, an urn contains balls numbered 1–56, and a second urn contains balls numbered 1–46. From the first urn, 5 balls are chosen randomly, without replacement and without regard to order. From the second urn, 1 ball is chosen randomly. For a \$1 bet, a player chooses one set of five numbers to match the balls selected from the first urn and one number to match the ball selected from the second urn. To win, all six numbers must match; that is, the player must match the first 5 balls selected from the first urn and the single ball selected from the second urn. What is the probability of winning the Mega Millions with a single ticket?
