If we sample from a small finite population without replacement, the binomial distribution should not be used because the event

Answer:

5/4324 = 0.001156337

Step-by-step explanation:

To better understand the hyper-geometric distribution consider the following example:

There are 100 senators in the US Congress, and suppose 60 of them are republicans so 100 - 60 = 40 are democrats).

We extract a random sample of 30 senators and we want to answer this question:

What is the probability that 10 senators in the sample are republicans (and of course, 30 - 10 = 20 democrats)?

The answer using the h-g distribution is:

$\large \frac{\binom{60}{10}\binom{100-60}{30-10}}{\binom{100}{30}}=\frac{\binom{60}{10}\binom{40}{20}}{\binom{100}{30}}$

Now, imagine there are 56 senators (56 lottery numbers), 6 are republicans (6 winning numbers and 50 losers), we extract a sample of 6 senators (the bettor selects 6 numbers). What is the probability that 4 senators are republicans? (What is the probability that 4 numbers are winners?).

<em>As we see, the situation is exactly the same,</em> but changing the numbers. So the answer would be

$\large \frac{\binom{6}{4}\binom{56-6}{6-4}}{\binom{56}{6}}=\frac{\binom{6}{4}\binom{50}{2}}{\binom{56}{6}}$

Now compute each combination separately:

$\large \binom{6}{4}=\frac{6!}{4!2!}=15\\\\\binom{50}{2}=\frac{50!}{2!48!}=1225\\\\\binom{50}{6}=\frac{50!}{6!44!}=15890700$

and now replace the values:

$\large \frac{\binom{6}{4}\binom{50}{2}}{\binom{56}{6}}=\frac{15*1225}{15890700}=\frac{18375}{15890700}=\frac{5}{4324}$

and that is it.

If the decimal expression is preferred then divide the fractions to get 0.001156337

Num 27. Please answer and explain if you have time but totally not needed

ohaa [14]

Answer:

a. d = $\sqrt{3}$

b. d = $2\sqrt{3}$

c. d = $s\sqrt{3}$

Step-by-step explanation:

to find the length of the longest diagonal of the cube at first you will find the length of the diagonal if its base

If the length of the side of a cube is x

∴the length of the diagonal of the base = $\sqrt{x^{2}+x^{2}}=\sqrt{2x^{2} }=x\sqrt{2}$

Now to find the length of the longest diagonal we will use Pythagoras with the side of the cube and the diagonal of the base

$d^{2}=(x\sqrt{2} )^{2} + x^{2}=2x^{2} +x^{2} =3x^{2}$

$d=\sqrt{3x^{2} }=x\sqrt{3}$

means the length of the side multiply by root 3

a. The length of the side is 1 so $d=\sqrt{3}$

b. The length of the side is 2 so $d=2\sqrt{3}$

c. The length of the side is <em>s s</em>o $d=s\sqrt{3}$
