Suppose that 3 balls are randomly selected without replacement from an urn containing 5 white and 8red balls. LetXiequal 1 if theith ball is white, and let it equal 0 otherwise.(a) Give the joint probability mass function ofX1andX2.(b) Give the joint probability mass function ofX1,X2, andX3.

The local farm is advertising a special on fresh picked peaches. the farm charges $4.25 to pick your own peck of peaches and $3.50 for each additional peck you pick. write an equation for the total cost of peaches in terms of the number of pecks. deine your variables. how much does it cost to pick 3 pecks of peaches?

The random variable x is the number of occurrences of an event over an interval of ten minutes. it can be assumed that the probability of an occurrence is the same in any two-time periods of an equal length. it is known that the mean number of occurrences in ten minutes is 5.3. the appropriate probability distribution for the random variable
