The probability that a newborn baby at the hospital is female is 50%. What is the probability that at least 2 babies of 3 childr

Answer:

0.25 is the probability

Step-by-step explanation:

In this question, we are tasked with calculating the probability that in a hospital on a certain day, at least 2 out of three babies born that day are female.

To calculate the probability , let’s list out some needed facts;

Let the probability of having a baby girl be g = 50% = 50/100 = 1/2 = 0.5

The probability of having a boy b will be 1-g = 1-0.5 = 0.5

Now, we have 3 babies and we want to find the probability of at lest two being girl.

Mathematically that would be ; ggb or ggg

since we are having at lest 2 girls

For the ggb, we have ; 0.5 * 0.5 * 0.5 = 0.125

For the ggg we have 0.5 * 0.5 * 0.5 = 0.125

In probability, once we have or, we add.

Thus 0.125 + 0.125 = 0.25

If the square root of 1 over 2 x - 10 added by 3, which inequality can be used to find the domain of f(x)?

jeyben [28]

From the description, we have the function $f(x)= \sqrt{ \frac{1}{2x-10}+3 }$
Since the square root cannot be a negative number, the only thing need to do to find the domain of the function $f(x)$ is take the expression inside the square rot and set it greater or equal than zero:
$\frac{1}{2x-10}+3 \geq 0$
$\frac{6x-29}{2x-10} \geq 0$
$\frac{6x-29}{2(x-5)} \geq 0$
$x \leq \frac{29}{6}$ or $x\ \textgreater \ 5$

We can conclude that we can use the inequality $\frac{1}{2x-10}+3 \geq 0$ to find the domain of $f(x)$ . Also, the domain of $f(x)$ is (∞, $\frac{29}{6}$ ]U(5,∞).
