Concept explainers
(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.

- On a game show, a contestant is given the digits 3, 4, and 5 to arrange in the proper order to form the price of an appliance. If the contestant is correct, he or she wins the appliance. What is the probability of winning when the contestant knows that the price is at least $400?arrow_forwardFind the probability of each event.
