From a sack of fruit containing 3 apples, 2 oranges, and 2 bananas, a random sample of 4 pieces of fruit is selected. Suppose X is the number of apples and Y is the number of oranges in the sample. (a) Find the joint probability distribution of X and Y. (b) Find P[CX,Y)EA], where A is the region that is given by {x,y) | X ys 2. From a sack of fruit containing 3 apples, 2 oranges, and 2 bananas,...
3. From a sack of fruit containing 3 oranges, 2 apples, and 3 bananas, a random sample of 4 pieces of fruit is selected. If X is the number of oranges and Y is the number of apples in the sample, find (a) the joint probability distribution of X and Y; (b) P[(X, Y) ∈ A], where A is the region that is given by {(x, y) | x + y ≤ 2}.
From a sack of fruit containing 3 oranges, 2 apples, and 2 bananas, a random sample of 5 pieces of fruit is selected. If X is the number of oranges and Y is the number of apples in the sample, the joint probability distribution of X and Y is given by the accompanying function. Determine the correlation coefficient

From a box of fruit containing 23 oranges and 1 apple a random sample of 2 pieces of fruit has been selected without replacement. Let X be the number of oranges and Y be the number of apples in the sample. What will the Variance of Y be?
From a box of fruit containing 37 oranges and 1 apple a random sample of 2 pieces of fruit has been selected without replacement. Let X be the number of oranges and Y be the number of apples in the sample. What will the expected value of X, E(X)?
From a box of fruit containing 47 oranges and 1 apple a random sample of 2 pieces of fruit has been selected without replacement. Let X be the number of oranges and Y be the number of apples in the sample. What will the correlation of X and Y be? (Hint the variance of X and Y same. Covariance is just negative of these variances. )
Suppose you are shopping for fruit at the grocery store. There are apples, bananas and oranges. In how many ways can you buy 10 items of fruit? For example, you can buy 5 bananas, 3 oranges, and 2 apples; you could also buy 10 bananas and 0 apples and oranges. In how many ways can you buy 10 items of fruit, where you have to have at least one banana, one orange, and one apple?
From a box of fruit containing 70 oranges and I apple a random sample of 2 pieces of fruit has been selected without replacement. Let X be the number of oranges and Y be the number of app Tsample What will the covariance of
2 3 Consider an economy that produces only three types of fruit: apples bananas, and oranges. In the base year (a few years ago), the production and price data are listed in the tables to the right. Base Year Quantity Fruit Apples Bananas 5,000 bunches Oranges Price 3,000 bags In the base year, nominal GUP was s In the current year, nominal GDP is $ (Round both answers to the nearest whole number.) $2 per bag $3 per bunch $5...
