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

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.
