There are 5 lemons and 3 limes in a fruit bowl. Two pieces of fruit are selected at random. Find the probability that the selected fruit are:
(a) two limes
(b) two different pieces of fruit

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.

How many ways are there to select 6 pieces of fruit from a huge box containing apples, oranges, lemons, and grapefruits? (The order in which the pieces are selected does not matter, only the type of fruit and not the individual pieces matter, and there are a lot more than 6 pieces of each fruit in the box.)
Two pieces of fruit are chosen at random from 2 apples, 3 oranges, and 4 bananas. Let X be the number of apples and let Y be the number of oranges. Find the moment generating function of X and Y.
Two pieces of fruit are chosen at random from 2 apples, 3 oranges, and 4 bananas. Let X be the number of apples and let Y be the number of oranges. Find the moment generating function of X and Y.
5. Five bowls are labeled 1 - 5. Bowl j contains j white and 5-j red balls. Example: Bowl 2 contains 2 white and 3 red balls. One bowl is selected at random and two balls are selected (without replacement). (a) What is the probability both balls are white? (b) What is the probability both balls are red? (c) What is the probability one ball is red and one ball is white? (d) Write out the probability distribution for the...
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 2 apples, 3 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[X,Y)EA], where A is the region that is given by {(x.y) | X ys 3. (a) Complete the joint probability distribution below. (Type...
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
1.Suppose we have two bowls full of candies. Each bowl contains four different flavours of candy – grape (which are purple), lemon (which are yellow), cherry (which are red) and raspberry (which are also red). (a) [1 Mark] We will randomly select one candy from each bowl. The outcome of interest is the flavour of each of the two candies. Write out the complete sample space of outcomes. (b) [1 Mark] Suppose instead that we randomly select one candy from...
3.23 Good Chips versus Lemons A chip supplier produces 95% good chips and 5% lemons. The good chips fail with probability 0.0001 each day. The lemons fail with probability 0.01 each day. You buy a random chip. Let T be the time until your chip fails. Compute E [T] and Var(T).
Bowl A contains 3 red and 1 white chips, and bowl B contains 3 red and 4 white chips. A chip is drawn at random from bowl A and transferred to bowl B. Compute the probability of then drawing a red chip from bowl B.
