lutik1710 [3]

Answer: $1-(\frac{364}{365})^n$

Step-by-step explanation:

Binomial probability formula :-

$P(x)=^nC_xp^x(1-p)^x$ , where P(x) is the probability of getting success in x trials, n is the total number of trials and p is the probability of getting success in each trial.

We assume that the total number of days in a particular year are 365.

Then , the probability for each employee to have birthday on a certain day :

$p=\dfrac{1}{365}$

Given : The number of employee in the company = n

Then, the probability there is at least one day in a year when nobody has a birthday is given by :-

$P(x\geq1)=1-P(x$

Hence, the probability there is at least one day in a year when nobody has a birthday = $1-(\frac{364}{365})^n$

Tom and Jerry have a pool with a diameter of 12 ft. What is the<br> circumference of the pool?

RSB [31]

Hello!

Answer:

$\large\boxed{C = 12\pi ft\text{ or } C = 37.68ft}$

$\text{Formula for the circumference of a circle:}$

$C = d\pi$

$\text{In this instance, d = 12 ft. Plug this value into the equation:}$

$C = 12\pi ft \text{ or } C = 37.68 ft (\pi = 3.14)$
