Uhhhhh probably C I’m not sure tho:/
Using the binomial distribution, there is a 0.9983 = 99.83% probability that at most eleven of the thirteen babies are girls.
<h3>What is the binomial distribution formula?</h3>
The formula is:
The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
For this problem, the values of the parameters are:
p = 0.5, n = 13
The probability that at most eleven of the thirteen babies are girls is:
In which
P(X > 11) = P(X = 12) + P(X = 13)
Then:
So:
P(X > 11) = P(X = 12) + P(X = 13) = 0.0016 + 0.0001 = 0.0017
0.9983 = 99.83% probability that at most eleven of the thirteen babies are girls.

Answer:
It means that the people that write the history books or articles or whatever else is used have decided to word what they're writing down and documenting as "important," and how sometimes that the limitations and reality of situations of the past change from each person's decision of either how to describe it, give it meaning, take meaning, and so on. It's saying that whoever is in charge of documenting things and deciding what goes in and what doesn't will be the version that future generations of people will study and debate, wether it was real or not.
Step-by-step explanation:
<span>Bob can buy a cake that costs 13.50 Pounds and serves 12 people. It means that he needs 5 cakes of that type ( 5 * 12 = 60 > 57, so everyone gets a slice ). It would cost totally: 5 * 13.50 = 67.50 Pounds. Another cake that Bob can buy costs 18.75 Pounds and it serves 20 people. Now he would need 3 cakes ( 3 * 20 = 60 > 57 ). So 3 * 18.75 = 56.25 Pounds. And because Bob wants to pay as little as possible for the cakes, he would choose the 2nd cake. Answer: Bob will have to pay 56.25 Pounds. </span>
