<h3 /><h3>What is probability?</h3>
Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are. The analysis of events governed by probability is called statistics.
Given that:
Four usual dice are thrown
Total of numbers on the top faces of these four dice = 13
we know that in a dice, the sum of the numbers on any two opposite faces is always 7.
So,1 is opposite 6,
2 is opposite 5
and 3 is opposite 4.
Now, when 4,3,1 and 5 are the numbers on the top faces, then 3,4,6 and 2 respectively are the numbers on the face touching the ground as they sum upto 7.
Hence, total o faces touching the ground =3+4+6+2=15.

Answer:
62 square units
Step-by-step explanation:
The area of a rectangular prism is the sum of the areas of its six faces. Opposite faces have the same area, so it is the sum of 3 pairs of faces. The area of one face of each pair is the product of the dimensions of that face. Those three areas are ...
• L·W
• W·H
• H·L
so the total surface area is ...
A = 2(LW +WH +HL)
For hand calculation, this can be simplified a bit to ...
A = 2(LW +H(L+W)) . . . . . requires one less multiplication
For your prism, the area is ...
A = 2(5·2 + 3(5+2)) = 2(10 +21) = 62 . . . square units
Answer:
John is 31
Ella is 25
Step-by-step explanation:
Let sister's age be x, then John's age is (x + 6). So from sentence 2,
(3x) - 2(x + 6) = 13
3x - 2x - 12 = 13
x = 13 + 12 = 25
and x + 6 = 31
