An urn contains 8 green and 9 white balls. Six balls are randomly drawn from the urn in succession, with replacement. That is, a

gulaghasi [49]

Answer:

The probability is 0.022

Step-by-step explanation:

Firstly, we need to get the total number of balls in the urn

mathematically, we have this as ;

8 + 9 = 17

now, the probability of selecting a white ball will be the number of white balls divided by the total number of balls

Mathematically, we have this as 9/17

Now, since the event is carried out with replacement, the probability for the six times is the same

So, we have the probability as;

(9/17)^6 = 0.022

Answer:

$\boxed{\sf \frac{15}{22} }$

Step-by-step explanation:

The radius of the circle is 7 cm.

The two legs of the triangles are 7cm as well.

Area of a trinagle is ( base × height )/2.

$\frac{7 \times 7}{2} =24.5$

Multiply the value by 2 since there are two triangles.

$24.5 \times 2 = 49$

Calculate the area of the circle.

$\pi r^2$

The radius is given.

$\pi (7)^2$

Take $\pi$ as $\frac{22}{7}$

$49(\frac{22}{7} )$

$=154$

Subtract the area of the two triangles from the area of the whole circle.

$154-49=105$

The area of the shaded part is 105 cm². The total area of the shape is 154cm².

$\frac{105}{154} =\frac{15}{22}$
