<h3>
Answer: Choice B</h3>
=======================================================
Explanation:
The requirements for a probability distribution are this
- The individual probabilities must be between 0 and 1, inclusive of both endpoints. We can say
where p is an individual probability. - The probabilities must sum to 1.
Condition #1 shown above allows us to rule out choice C due to -0.10 not being in the interval from 0 to 1.
We can also rule out choice D since the probabilities sum to this
0.20+0.15+0.20+0.20+0.20+0.20 = 1.15
The sum is too large. The sum needs to be 1.00 or just 1.
So that leaves choice A or choice B as the possible answer. Both distributions fit conditions #1 and #2 as shown above (I'll let you confirm these facts). However, choice A is ruled out because that distribution is considered fair. Each probability for choice A is equal, so each side of the cube is equally likely to be landed on.
For choice B, the probabilities are different, so we don't have a fair cube here and it is considered loaded or biased.
Answer:
(D) and nice work with me in both of this ok meaning made by my lines

Answer:
See explanation above
Step-by-step explanation:
This problem is very similar to one I solved a few moments ago. First we need to know how much it rain during the month of august the first 15 days of august. We only know how much it rain from the 15th through the end of the month.
So if you want to know the total rainfall of the month, you only need to sum the amount of the rainfall from the first 15 days of august and the last days of the month.
To help you out, I will use the same data of the other problem, which was 8.33 cm for the first 15 days, and 4.65 for the last 15 days of august.
If you sum 8.33 and 4.65:
8.33 + 4.65 = 12.98 cm
This would be (theorically speaking) the total rainfall during this month. Now, if it's the same exercise that you have, then good, use this answer, but if it's not then, all you need to do is put the value for the first 15 days and do the sum with 4.65 cm to get the total.
Answer:
The rate is 
degree per hour.
Step-by-step explanation:
Given : A scientist conducted an experiment. Due to chemical reaction, the temperature of a compound rose 
degree every 
hour for a limited time.
To find : What was the rate, in degrees per hour that the temperature of the compound rose ?
Solution :
In every hour the temperature of a compound rose degree
To get the rate, in degrees per hour,
In every 1 hour the temperature of a compound rose is
degree
degree/hr
degree/hr
Therefore, the rate is degree per hour.
