Answer:
The probability of getting two numbers whose sum is greater than 9 and less than 13 is
Step-by-step explanation:
Given : A single 6-sided die is rolled twice.
To find : The probability of getting two numbers whose sum is greater than 9 and less than 13 ?
Solution :
The set of 36 equally likely outcomes,
1 2 3 4 5 6
1 (1, 1) (1, 2) (1, 3) (1, 4) (1, 5) (1, 6)
2 (2, 1) (2, 2) (2, 3) (2, 4) (2, 5) (2, 6)
3 (3, 1) (3, 2) (3, 3) (3, 4) (3, 5) (3, 6)
4 (4, 1) (4, 2) (4, 3) (4, 4) (4, 5) (4, 6)
5 (5, 1) (5, 2) (5, 3) (5, 4) (5, 5) (5, 6)
6 (6, 1) (6, 2) (6, 3) (6, 4) (6, 5) (6, 6)
Getting two numbers whose sum is greater than 9 and less than 13
The favorable outcome is (4,6),(5,5),(5,6),(6, 4),(6, 5),(6, 6) = 6
The probability is given by,
Therefore, The probability of getting two numbers whose sum is greater than 9 and less than 13 is
You are wrapping a gift box. The length of ribbon = length + width + height of box.
<u>Solution:</u>
Given, You are wrapping a gift box.
You want to tie a ribbon around the box, so that whenever the ribbon intersects an edge of the box, its distance to the nearest corner is 1/3 the length of the box.
We have to find how long must the ribbon be?
The figure of this problem is attached below
Now, assume we started to tie at one edge, then next we can tie at straight parallel edge, we can continue till our process ends.
Then, total length of the ribbon = length of box + width of box + height of box.
Hence, the length of ribbon = length + width + height of box.
