Answer:

1/2 or 50%

Step-by-step explanation:

You can use some casework to find your answer.

The first case - only two of the coins are heads.

The possible ways that this could be are:

THH

HTH

HHT

The second case - all three coins are heads.

In this instance, there is only one way that this could happen:

HHH

This is a total of 4 desired outcomes out of 2*2*2=8 possible outcomes, which is a probability of 4/8=1/2. Hope this helps!

In the first diagram the value of k is 10 and in the second diagram the value of k is 15/2.

<h3>What is the triangle?</h3>

The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.

In the first diagram:

The sum of the 5k + 20 and 7k + 40 is 180

5k + 20 + 7k + 40 = 180

12k + 60 = 180

12k = 180 -60

12k = 120

k = 10

In the second diagram:

The sum of the two interior angles is equal to the exterior angle.

40 + 12k + 10 = 8k + 80

4k = 30

k = 30/4 = 15/2

Thus, in the first diagram the value of k is 10 and in the second diagram the value of k is 15/2.
