Hello! What type of work is that so I can specifically know! :)
Please take another photo of this problem sheet and share it, showing the problem statement right side up. Next, please do as much as you can on the first part of this problem. Then I'd gladly comment on your work. If you can't do that, then at least ask questions the answers to which might help you get started.
Answer:
b. One in Five
Step-by-step explanation:
To calculate probability, we need to know the formula: 
in this case the probability is given in its decimal form, which is = 0.20
∴ to be able to use our formula easily, we will need to convert the probability to its fraction form.
which is 0.20 =
(<em> to do this, just simply put a 1 under the decimal point and replace the remaining values of 20 with zeroes)</em>
reducing
to its simplest form gives
.
Hence, relating it to our formula, we can see that the number of possible out comes is = 1
and the total number of outcomes = 5.
This means that the probability that the order will execute before the same of closing is the same as 1 in 5
If the design is the cube in the second answer then it would have a surface area of 25 cm per face of the cube because to get the surface are you would multiple side by side of a face and then to get the full cubes surface area multiple one faces surface area by six because the cube has six faces and to get the volume you cube the side length of 5cm to get 125cm cubed. Hope this helps.
