Step-by-step explanation:
<u>Inverse Proportion</u>
The time needed to complete a job is inversely proportional to the number of men working on it.
It means the more men working, the less time needed to complete the job.
We know 20 men can complete the job in 15 days. If the job must be completed in 12 days, then more men are needed, thus the number of men needed is:
25 men are needed which means 25-20 = 5 more men should be added.
5 more man should be added

Answer:
D) 1/36
Step-by-step explanation:
You are trying to roll a 3 the first time, and then a 5 the second time. This means that order matters.
It is given to you, that you are rolling a standard die (6-sides). The dice is ordered in the following: 1, 2, 3, 4, 5, 6
The first time, you are rolling for a 3. Note that there is only one 3 in the sequence, so your chance of rolling a 3 is 1 out of 6: 1/6.
The second time, you are rolling for a 5. Note that there is only one 5 in the sequence, so your chance of rolling a 5 is 1 out of 6: 1/6.
Next, multiply the two fractions together to find the probability of rolling a 3 and then a 5:
1/6 x 1/6 = (1 x 1)/(6 x 6) = 1/36
D) 1/36 is your answer.
