Answer:

The couple having 3 children

Step-by-step explanation:

For each children, there is a 50% probability that it is a girl and a 50% probability that it is a boy.

Suppose a couple decided to keep having children until they have a girl.

The probability that they have 3 children, that is 2 boys before a girl is:

The desired outcome is two boys then a girl. Each of these outcomes has a 50% probability. So

The probability that they have 4 children, that is 3 boys before a girl is:

The desired outcome is three boys then a girl. Each of these outcomes has a 50% probability. So

The probability that they have 5 children, that is 4 boys before a girl is:

The desired outcome is four boys then a girl. Each of these outcomes has a 50% probability. So

The probability that they have 6 children, that is 5 boys before a girl is:

The desired outcome is five boys then a girl. Each of these outcomes has a 50% probability. So

Which of these is most likely?

The largest probability is the one of them having three children, that is, two boys before a girl.

So the correct answer is:

The couple having 3 children

The formula for the volume V of a cylinder is V=πr2h, where r is the radius of the base and h is the height of the cylinder. Sel
Alja [10]

Answer:

see explanation

Step-by-step explanation:

Given

V = πr²h ( isolate h by dividing both sides by πr² )

\frac{V}{\pi r^2} = h

When V = 36π , r = 3 , then

h = \frac{36\pi }{\pi (3)^2} = \frac{36\pi }{9\pi } = 4 cm
