(a)
To find: The probability of twins who were male.
(b)
To show: The probability that a pair of twins consists of two males is
of twins who were male.
(c)
To find: An estimate for the value of p using the answers of parts (a) and (b) and using the fact that 5,844 are the pairs of two males.
(d)
To find: An expression for the probability that a pair of twins is female, similar to part (b).
(e)
To find: An estimate for the value of p by using the parts from (a) to (d), and using the fact that 5612 of 17,798 twin pairs were female.
(f)
To find: An expression for the probability that a pair of twins consists of one female and one male, similar to parts (b) and (d).
(g)
To find: An estimate for the value of p by using the parts from (a) to (f), and using the fact that 6432 of 17,798 twin pairs consisted of one male and one female.
