You roll a 6-sided die.<br> What is P(prime)?<br><br> Write your answer as a percentage.

$\huge \underline\text {Hello There!!}$

<h3><u>Given</u></h3>

Rolled A six-sided dice.

P(Prime) as percentage

<h3><u>Solution</u></h3>

Total Possible Outcomes= 1, 2, 3, 4, 5, 6.

So, No. of possible Outcomes= 6

Prime number of the dice= 2, 3, 5

So, No. of favorable outcomes of Prime number= 3

$\text{Probability of an event= }$

$\frac{ \text{favorable no. of outcome}}{ \text{total no. of outcome}} \times 100$

$\text{Percentage of Probability getting P(Prime) number on face of dice} =$

$\frac{3}{6} \times 100 \\ \\ = \cancel \frac{3}{6} \times 100 \\ \\ = \frac{1}{ \cancel2} \times \cancel{100} \\ \\ = 50\%$

$\therefore \% \text{ Probability of getting prime number is \red{50} \red\%}$

Marta is solving the equation s=2πrh+2πr^2 for h. which should be the result?

Marta_Voda [28]

Answer: First option.

Step-by-step explanation:

Marta needs to subtract $2\pi r^2$ from both sides of the equation:

$s=2\pi rh+2\pi r^2$

$s- 2\pi r^2=2\pi rh+2\pi r^2- 2\pi r^2$

$s- 2\pi r^2=2\pi rh$

Now she needs to divide both sides of the equation by $2\pi r$ , then:

$h=\frac{s- 2\pi r^2}{2\pi r}$

Rewriting:

$h=\frac{s}{2\pi r}-\frac{2\pi r^2}{2\pi r}$

Simplifying, she should get:

$h=\frac{s}{2\pi r}-r$

This matches with the first option.
