Concept explainers
(a)
To find: the minimal chance that one will have twins, if no one took a fertility drug.
(a)
Answer to Problem 7RE
10.6%
Explanation of Solution
Given:
The probability of females getting twins is
Calculation:
Suppose X is the number of women who have twins while taking drugs for futility.
Success is about making twins.
Failure does not mean having twins.
The trails are independent.
Hence X is binom (10, 0.1)
Let X be the number of pregnant women who, if they do not take fertility drugs, have twins.
The probability of getting twins is
The variable X is a binomial
The probability of minimum one pregnant woman getting twins is
If both of them are not taking fertility medication, there is a 10.6 percent risk that at least one has twins.
(b)
To find: the minimal probability that one would have twins, if both of them were to take clomid.
(b)
Answer to Problem 7RE
65%
Explanation of Solution
Given:
Calculation:
Probability that from 10 pregnant minimum one would have twin is
There is 65% possibility that among 10 pregnant women minimum one has twin.
(c)
To find: the probability that if half were taking clomid, at minimum one would have twins.
(c)
Answer to Problem 7RE
Explanation of Solution
Given:
Calculation:
The chance that if about half of them take fertility drugs, at least one has twins is,
If only half of them take fertility drugs, there is a 97.8 percent risk that at least one has twins.
