For each problem, show the proper work needed for FRQ’s and find the answer. For problems with a *, you must show the mathematical notation also (IE ( 9 3 )(.8)3 (.2)6 ). You do not have to provide context for the answer unless specifically asked. NOTE: Only need help with the answers from the seventh day through the twelfth day. On the seventh day of Christmas, my true love gave to me: Seven Swans A-swimming. If the probability of a swan drowning is uniformly distributed for number of years from 0 to 8, find the probability that it drowns before it is 2.5 years old. On the eighth day of Christmas, my true love gave to me: Eight Maids A-milking. The probability of the quality of milk (scale of 1-4 with four being delicious) is shown: Find the expected value and standard deviation of the quality of milk for one cow. Quality scale 1 2 3 4 Probability .3 .5 .15 .05 On the ninth day of Christmas, my true love gave to me: Nine Ladies Dancing. If the probability of a dancing lady accepting an invitation to dance is 0.22, find and INTERPRET the expected number of ladies you would have to ask before one accepts. On the tenth day of Christmas, my true love gave to me: Ten Lords A-leaping. If the probability of a lame (not being able to leap) leaping lord is 0.24, find the probability of getting your first lame leaping lord before the third attempt. On the eleventh day of Christmas, my true love gave to me: Eleven Pipers Piping. If the probability of frozen pipes is 0.63, find the probability of 8 or more frozen pipes out of the eleven. On the twelfth day of Christmas, my true love gave to me: Twelve Drummers Drumming. If the probability of a dribbling drummer is 0.48, find the standard deviation of the dribbling drummers drumming for twelve drummers drumming
