Let us assume that a turkey is classified by its weight as low, medium, or high. we can also assume that 1% of turkeys are classified as low, 98% as medium, and 1% as high. a sample of 20 turkeys is selected for weighing. let x, y, and z represent the number of turkeys that are independently classified as low, medium, and high weight, respectively. a. what is the expected number of medium weight turkeys?
b. find p(x=1,y=18,z=2).
c. find p(x≤1,y=18,z=2).
d. what are the name and values of the parameters of the joint probability distribution of the joint distribution of x, y, and z?
e. what are the name and values of the parameters of the marginal probability distribution of x?

Naruto is choosing between two venues that will deliver food to his house. with probability 1/3 he will choose ramen mania (r), and with probability 2/3 he will choose sushi (s). if he chooses r, 15 minutes after making the call, the remaining time it takes the food to arrive is exponentially distributed with average 10 minutes. if he orders s, 10 minutes after making the call, the time it takes the food to arrive is exponentially distributed with an average of 12 minutes. given that he has already waited 25 minutes after calling, and the food has not arrived, what is the probability that he ordered from r? i am really stuck on how to set this up, so if you could be extra clear, that would be super ! in advance
