A cube is numbered 1 through 6. If the cube is rolled twice, how many of the possible outcomes will have two even

Step-by-step explanation:

rolling the die twice as one event we get 6×6 = 36 possible outcomes.

rolling an even number on the first try gives us 3 desired outcomes (2, 4, 6).

rolling it a second time gives us again 3 desired outcomes.

in total we have

3×3 = 9 such outcomes with 2 even numbers.

the probability for that is then

9/36 = 1/4 = 0.25

FYI - we have also 9 possible outcomes for the first roll being odd and the second being even, 9 possible outcomes for the first being even and the second being odd, and 9 possible outcomes for both being odd.

together with the 9 for both being even we get the full 36 possible outcomes. no other event is possible.

Answer:

P = $\frac{4}{25}\\$

Step-by-step explanation:

Big circle area:

$A=\pi r^{2} =\pi (10)^{2} =100\pi$

Smaller circle área:

$A=\pi (4)^{2} =16\pi$

Probability:

$P=\frac{16\pi }{100\pi } =\frac{4}{25}$

Hope this helps

Let's compare the scientific notation representation of two of these numbers. 0.0000004 = 4.0 x 10 ⁻⁷ and 1,080,000,000 = 1.08 x

Step-by-step explanation:

Scientific notation is a quick way to represent a number using powers of base ten. This notation is used to be able to express very large or very small numbers very easily.

The numbers are written as a product:

a * 10ⁿ

where:

a is a real number greater than or equal to 1 and less than 10, to which a decimal point is added after the first digit if it is a non-integer number.
n = a whole number, which is called an exponent or an order of magnitude. Represents the number of times the comma is shifted. It is always an integer, positive if it shifts to the left, negative if it shifts to the right.

Comparing what is equal to these two numbers when they are written in scientific notation you can see that the value of a is such that 1 ≤ a <10

Comparing what is different from these two numbers when they are written in scientific notation, you can see that the value of the exponent n in both numbers is different, one being positive, indicating that it is a very large number, and the other negative, indicating that it is It is a very small number that is between 0 and 1.
