4. the stock market goes up more often that it goes down. assume the probability that the stock market goes up in a randomly selected month is 60%. a. what is the probability the stock market goes up 12 months in a row? b. what is the probability it goes down 12 months in a row? c. what is the probability it goes up six months in a row and then goes down six months in a row? note this is one specific pattern . d. how many different ways are there for the stock market to go up six times in 12 months? hint: there is a function in r for “n choose k”; the syntax is “choose(n, k)”. e. use your answers to the prior two questions to calculate the probability that the stock market goes up exactly six months out of 12 in any order. f. what is the probability the stock market goes up 6 or more months in a year? hint: repeat the prior calculation for 7, 8, 9, 10, 11, and 12 times. finally, calculate the probability for the union of these mutually exclusive events. g. what are the expected value and the standard deviation of the number of months the stock market rises in a year (12 months)?
