Consider a population with m+n elements, where n of them are 1 and m of them are 0. Then sample two points randomly from the population. a) Suppose we sample them without replacement, which corresponds to the random sample. Calculate the probability of the outcomes (0,0), (0,1), (1,0) and (1,1). b) Suppose we sample them with replacement. Calculate the probability of the outcomes (0,0), (0,1), (1,0) and (1,1).

Can someone please answer this ASAP? 3) n people put their car keys in the center of a room where the keys are mixed together. Each person randomly selects one. Let Y be the number of people who can select their own key. Find the mean and variance of Y . (Hint: Use Xi = 1 if ith person has a match, and Xi = 0 otherwise.)

There are “n” candies in a jar. 7 of the candies are red. The rest of the candies are blue. Kevin takes at random a candy from the jar. He eats the candy (clue:   is this a "replacement" or "without replacement" problem?). Kevin then takes at random another candy from the jar (clue: this second candy is picked from how many total candies? less or equal to "n"?) . He eats the candy. The probability that Kevin eats 2 red...

1/ Imagine a party with n people. When a person comes to the party they go and shake hands with a few other people (but not necessarily everyone - in fact there can be unfriendly people who do not shake hands with anyone!).

For example, suppose 3 people attend the party and everyone shakes hand with...
