Considering the given probability distributions, distribution D is valid.
<h3>When a probability distribution is valid?</h3>
A probability distribution is valid if:
- There are no negative probabilities.
- The sum of all probabilities is of 1.
In this problem, only distribution D has a sum of 1, hence it is the only valid distribution.

Step-by-step explanation:
Answer:
-9
Step-by-step explanation:
We are told in the question that:
Xavier climbs 9 feet up into an apple tree.
The direction symbol or sign for upwards movement = Positive (+) sign
If Xavier would climb back down , he will climb back down 9 feet as well
The direction symbol or sign for downwards movement = Negative (-) sign
Since we know the distance (or how far) he has to climb by downwards is also 9 feet, therefore, the integer that represents the direction and how far he will climb to get back down to the ground is -9
I can do the first part, but the second part is confusing...

Find out how many plates Mike can pack in a minute.
60 (an hour) / .75 (3/4) = 45
180 / 45 = 4
Mike can pack 4 plates per minute.
Since Mike only packs 4 ppm, Lucy packs faster, with 5 plates per minute!
