Six customers enter a three-floor restaurant. Each customer decides on which floor to have dinner. Assume that the decisions of

Firdavs [7]

<h2>Answer:</h2>

The probability that exactly one customer dines on the first floor is:

0.26337

<h2>Step-by-step explanation:</h2>

We need to use the binomial theorem to find the probability.

The probability of k success in n experiments is given by:

$P(X=k)=n_C_k\cdot p^k\cdot (1-p)^{n-k}$

where p is the probability of success.

Here p=1/3

( It represents the probability of choosing first floor)

k=1 ( since only one customer has to chose first floor)

n=6 since there are a total of 6 customers.

This means that:

$P(X=1)=6_C_1\times (\dfrac{1}{3})^1\times (1-\dfrac{1}{3})^{6-1}\\\\\\P(X=1)=6\times (\dfrac{1}{3})\times (\dfrac{2}{3})^5\\\\\\P(X=1)=0.26337$

How do you do square roots totem pole

Igoryamba

Well the square root of a number is a number times its self equaling the number you're getting the square root of. For example:

<span>√ 25
</span>
To get sqrt of 25 we need to find a number times its self that equals 25. Lets try 8.

8 x 8 = 64

Well thats much too high, We'll try a lower number.

4 x 4 = 16

Just a little higher.

5 x 5 = 25

Since 5 times itself equals 25 that makes it the sqrt.

So, the √ 25 is 5.
