The probability that the sum of the two number will be less than 4 is ![\frac{1}{12}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B12%7D)
Explanation:
It is given that Mike rolls two number cubes.
It is given by the sample space S.
Let A be the event that the sum of the two number will be less than 4.
The sample space is given by
![S=\left\{\begin{array}{l}(1,1),(1,2),(1,3),(1,4),(1,5),(1,6) \\(2,1),(2,2),(2,3),(2,4),(2,5),(2,6) \\(3,1),(3,2),(3,3),(3,4),(3,5),(3,6) \\(4,1),(4,2),(4,3),(4,4),(4,5),(4,6) \\(5,1),(5,2),(5,3),(5,4),(5,5),(5,6) \\(6,1),(6,2),(6,3),(6,4),(6,5),(6,5)\end{array}\right.](https://tex.z-dn.net/?f=S%3D%5Cleft%5C%7B%5Cbegin%7Barray%7D%7Bl%7D%281%2C1%29%2C%281%2C2%29%2C%281%2C3%29%2C%281%2C4%29%2C%281%2C5%29%2C%281%2C6%29%20%5C%5C%282%2C1%29%2C%282%2C2%29%2C%282%2C3%29%2C%282%2C4%29%2C%282%2C5%29%2C%282%2C6%29%20%5C%5C%283%2C1%29%2C%283%2C2%29%2C%283%2C3%29%2C%283%2C4%29%2C%283%2C5%29%2C%283%2C6%29%20%5C%5C%284%2C1%29%2C%284%2C2%29%2C%284%2C3%29%2C%284%2C4%29%2C%284%2C5%29%2C%284%2C6%29%20%5C%5C%285%2C1%29%2C%285%2C2%29%2C%285%2C3%29%2C%285%2C4%29%2C%285%2C5%29%2C%285%2C6%29%20%5C%5C%286%2C1%29%2C%286%2C2%29%2C%286%2C3%29%2C%286%2C4%29%2C%286%2C5%29%2C%286%2C5%29%5Cend%7Barray%7D%5Cright.)
Hence, the total probability of the sample space is ![P(S)=36](https://tex.z-dn.net/?f=P%28S%29%3D36)
To determine the probability of the sum of the two number will be less than 4, we need to add the outcomes of the two numbered cubes which results in the value less than 4.
Thus, we get,
![A=(1,1),(1,2),(2,1)](https://tex.z-dn.net/?f=A%3D%281%2C1%29%2C%281%2C2%29%2C%282%2C1%29)
Thus,
![P(A)=3](https://tex.z-dn.net/?f=P%28A%29%3D3)
The probability that the sum of the two number will be less than 4 is given by
![\frac{P(A)}{P(S)} =\frac{3}{36}](https://tex.z-dn.net/?f=%5Cfrac%7BP%28A%29%7D%7BP%28S%29%7D%20%3D%5Cfrac%7B3%7D%7B36%7D)
![\frac{P(A)}{P(S)} =\frac{1}{12}](https://tex.z-dn.net/?f=%5Cfrac%7BP%28A%29%7D%7BP%28S%29%7D%20%3D%5Cfrac%7B1%7D%7B12%7D)
Thus, the probability that the sum of the two number will be less than 4 is ![\frac{1}{12}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B12%7D)
B $2.85
You multiply the $1.60 by 3 and then subtract 1.95 from that answer.
The answer is 80%

Answer:
560m³
Step-by-step explanation:
Cuboid : length = 16, width = 5, height = 4
Prism : base = 16, perpendicular height = 6, height = 5
V = volume cuboid + volume prism
V = 16 x 5 x 4 + (16 x 6 : 2 x 5) = 560m³
The answer would be 10.27 each person has to pay
