You actually own your mom and dad 49.5 dollars each.
Answer:
0.3702
Step-by-step explanation:
For each newborn, there are only two possible outcomes. Either it is a female, or it is a male. The probability of a newborn being male or female is independent from other newborns. So we use the binomial probability distribution to solve this problem.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
Assume each newborn baby had a probability of approximately 0.54 of being female and 0.46 of being male. For a family of four children, let X = number of children who are girls.
This means that
Find the probability that the family has two girls and two boys.
Two girls, so
The answer is 0.3702
