What is the chance of rolling a 4 with a single dice 3 times

Answers

The chance of rolling a 4 is 1/6 .

If you already have one, then the chance of rolling another one is 1/6 .

If you already have two, then the chance of rolling another one is 1/6 .

So, starting from the beginning, the chance of rolling three of them
IN THREE TOSSES is

(1/6) x (1/6) x (1/6) = 1/216 = about 0.46 % .

The question actually just says "the chance of rolling a 4 three times".
If you just look at it that way, the chance could be 100% ... it doesn't
say anything about how many tosses you get, and you're just going to
keep rolling that durn cube until you get three 4's.

3/18. This is because you roll a 4 3 times, and I'm assuming it's a standard 6 sided die (singular for dice). 3 x 6 = 18 and 3 x 1 = 3.

Answer:

3077.2

Step-by-step explanation:

A circle's mass is found by

Pie times R^2

7^2 is 49, times 3.14 is 153.86

then you Multiply 153.86 by 20 which gives you 3077.2

Volume of a cylinder = pi r^2 * h
Pi 7^2 * 20
Volume = 49 pi

Density = mass/ volume
2.5= mass/ 49 pi
Mass= density * volume
= 2.5*49 pi
= 245/2 pi
= 384.845...
=384.8 g to 1 dp

Answer= Volume

There are a total of 20 lions, tigers and bears. If the number of tigers is 2 more than the number of lions and the number of bears is 1 more than the number of tigers, find the number of each.

Answers

Number of tiguers: x + 2
Number of Lions: x
Number of bears:(x+2)+1=(x+3)

We can suggest this equation:
(x+2) + (x)+(x+3)=20

3x+5=20
3x=20-5
3x=15
x=15/3
x=5.

Therefore:
Number of tiguers: x + 2=5+2=7
Number of Lions: x=5
Number of bears:(x+2)+1=(x+3)=5+3=8.

Answer: there are 7 tiguers, 5 lions and 8 bears.

Final answer:

In the problem, if we denote the number of lions as x, the number of tigers as x+2, and the number of bears as x+3, and considering that the total of all these animals is exactly 20, we can form and solve a simple algebraic equation. We will find that there are 5 lions, 7 tigers, and 8 bears.

Explanation:

This is a problem of simple algebra. According to the problem, let's represent the number of lions as x, the total number of tigers as x + 2 (since it's two more than the lions), and the number of bears as x + 3 (1 more than the number of tigers).

The problem states the total number of all these animals as 20, so we can set up the following equation: x + x + 2 + x + 3 = 20.

Solving this algebra equation gives you:

3x + 5 = 20

Subtracting 5 from both sides gives us:

3x = 15

Dividing both sides by 3 gives us:

x = 5

So, the number of lions is 5, the number of tigers is 7 (5 + 2), and the number of bears is 8 (7 + 1).
