Answer the (a) Determine the value that is missing in the table. (Hint: what are the requirments for a (b) Find the probability that x is at least 2 . that is find P(x 2 2). (c) Find P(x 5 1). Describe what the resulting value represents within the given context. ((1) Expand the table above by adding columns to the right and nd the mean [1 (expected value) and standard deviation 0 of this probability distribution. Answer the two following questions in relation to probability distrbution concepts. (a) What is meant by the term "expected value"? (b) Suppose the expected value of a lottery ticket is -$1.35. Does this mean that you will lose exactly $1.35 every time you buy a ticket? Explain your answer briey. List the 5 requirements needed for an experimenb'procedure to be considered a binomial
