Probability someone chosen at random will not have brown hair = 1/6

<h3>Probability of two variables</h3>

The number of girls = 15

The number of boys = 15

The total number of children = 15 + 15 = 30

Probability that someone chosen at random will have a brown hair, P(Brown hair) = 5/6

P(Brown hair) + P(Not Brown hair) = 1

5/6  +  P(Not brown hair) = 1

P(not brown hair) = 1 - 5/6

P(not brown hair) = 1/6

Therefore, if someone is chosen at random, probability that they will not have brown hair = 1/6

Dolve the equation <br> 11q-6=3q+8q
Amanda [17]

Answer:

no solution

Step-by-step explanation:

Simplifying

11q + -6 = 3q + 8q

Reorder the terms:

-6 + 11q = 3q + 8q

Combine like terms: 3q + 8q = 11q

-6 + 11q = 11q

Add '-11q' to each side of the equation.

-6 + 11q + -11q = 11q + -11q

Combine like terms: 11q + -11q = 0

-6 + 0 = 11q + -11q

-6 = 11q + -11q

Combine like terms: 11q + -11q = 0

-6 = 0

Solving

-6 = 0

Couldn't find a variable to solve for.

This equation is invalid, the left and right sides are not equal, therefore there is no solution.

Fencing How much fencing is required to enclose a circular garden whose radius is 28 ​m? Use 3.14 for . About nothing m of fenci
Andru [333]

Answer:

175.84 m

Step-by-step explanation:

Given that:

A circular garden which has a radius of 28 m.

\pi = 3.14

To find:

The fencing required to enclose the circular garden ?

Solution:

Here, we are given a circle and its radius.

We are required to find the perimeter of the circle in order to find the fencing required to enclose the circular garden..

Formula for finding the perimeter of a circle is:

Perimeter = 2\pi r

where r is the radius of the circle.

Using the given values in the formula:

Perimeter = 2\times 3.14 \times 28 = <em>175.84 m</em>

Therefore, 175.84 m of fencing is required.
