<h2>The answer is Option A!</h2>
<h3>Why so??</h3>
Let's see what complex numbers are!
Now we know,
So!
And thus we get the answer!
Answer:
The probability of all three children being girls is 0.125.
Step-by-step explanation:
The events of a boy being born and the girl being born is equally likely.
That is, P (G) = P(B) = 0.50.
The gender of <em>n</em>th baby born is independent of the gender of the (<em>n</em> - 1)th baby born.
Compute the probability of all girls as follows:
P (All three girls) = P (G) × P (G) × P (G)
Thus, the probability of all three children being girls is 0.125.

Answer:
a) The probability that at least 5 ties are too tight is P=0.0432.
b) The probability that at most 12 ties are too tight is P=1.
Step-by-step explanation:
In this problem, we could represent the proabilities of this events with the Binomial distirbution, with parameter p=0.1 and sample size n=20.
a) We can express the probability that at least 5 ties are too tight as:
The probability that at least 5 ties are too tight is P=0.0432.
a) We can express the probability that at most 12 ties are too tight as:
The probability that at most 12 ties are too tight is P=1.
