AP STATISTICS Name ________________________ THE TWELVE DAYS OF STATISTICS  On the first day of Statistics, my true love gave to me: A Partridge in a Pear Tree . If the probability of getting a partridge is 0.58 and the probability of getting a pear tree is 0.76, and these are independent events, find the probability of getting a partridge and a pear tree.  On the second day of Statistics, my true love gave to me: Two Turtle Doves. If the probability of a female turtle dove is 0.53, find the probability of at least one female turtle dove in the pair.  On the third day of Statistics, my true love gave to me: Three French Hens. If the probability of a hen truly having French citizenship is 0.81, find the probability of exactly two French hens out of the three.  On the fourth day of Statistics, my true love gave to me: Four Calling Birds. If the probability of a bird actually calling is 0.63, find the probability of finding the first calling bird on the third attempt.  On the fifth day of Statistics, my true love gave to me: Five Golden Rings. If the probability of getting a real golden ring is 0.72, find the probability of getting three or fewer golden rings out of the five 5 gold rings.  On the sixth day of Statistics, my true love gave to me: Six Geese A-laying. If the probability of an authentic laying goose is 0.83, find the probability of getting the first laying goose on the fourth trial.  
On the seventh day of Statistics, my true love gave to me: Seven Swans A-swimming. If the probability of a swan drowning is 0.23, find the probability of exactly 4 out of the 7 swans drowning.  On the eighth day of Statistics, my true love gave to me: Eight Maids A-milking. If the probability of getting a sour maid a-milking is 0.38, find the expected number of sour maids a-milking in the group of 8.  On the ninth day of Statistics, my true love gave to me: Nine Ladies Dancing. If the probability of a dancing lady accepting an invitation to dance is 0.18, and the probability that a she can waltz is .56, find the probability that a dancing lady is asked to dance and knows how to waltz.  On the tenth day of Statistics, my true love gave to me: Ten Lords A-leaping. If the probability of a lame leaping lord is 0.24, find the probability of getting your first lame leaping lord after the sixth attempt.  On the eleventh day of Statistics, my true love gave to me: Eleven Pipers Piping . If the probability of a frozen pipe is 0.63, and the probability of frozen pipes and that the piper is sick is .31. Find the probability that the piper is sick given that his pipe is frozen.  On the twelfth day of Statistics, 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.  If you round all answers to three significant digits, the sum of the twelve answers should be 14.0479.
