24
The least common multiple
of 3 and 8 is 24.
Given:
The two statements.
To find:
The probability of an impossible event.
The probability of a certain event.
Solution:
Formula for probability is:
For an impossible event, the possible favorable outcomes is 0. So,
For a certain event (sure event), the possible favorable outcomes is equal to total number of outcomes. So,
Therefore, an event that is impossible has probability 0 and an event that is certain has probability 1.
Is the all of the problem
Yes, 2.8 cm, 4.0 cm, and 2.8 cm could be the side lengths of a triangle ⇒ B
Step-by-step explanation:
In any triangle:
- The sum of any two sides is greater than the third side
- Add the smallest two numbers if their sum is greater than the largest number, then the numbers can formed the lengths of sides of a triangle
∵ The lengths of the segments are 2.8 cm , 4.0 cm and 2.8 cm
∵ The smallest segments are 2.8 cm , 2.8 cm
- Find their sum
∴ The sum of their length = 2.8 + 2.8
∴ The sum of their length = 5.6 cm
The length of the largest segment is 4.0 cm
∵ 5.6 cm > 4 cm
∴ 2.8 cm , 4.0 cm , 2.8 cm can formed a triangle
Yes, 2.8 cm, 4.0 cm, and 2.8 cm could be the side lengths of a triangle
