Using the probability concept, the correct statement is:
B. P(hibiscus|red) = P(hibiscus).
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
For item a, the probabilities are:
- P(yellow|rose) = 45/105 = 0.4286.
- P(yellow) = 135/315 = 0.4286.
Same probabilities, hence the statement that they are different is false.
For item b, the probabilities are:
- P(hibiscus|red) = 80/120 = 2/3.
- P(hibiscus) = 210/315 = 2/3.
Equal, hence this is the correct statement.

Answer: True</h3>
Often we replace "units" with something like "feet" or "meters"
examples: square feet, square meters, square yards, etc
The "square" refers to the idea that any surface area can be unwrapped and lay flat, then you can break the area of that flat figure into smaller squares. A good example of this is a dice has 6 faces and each face is a square itself, so the total surface area is the sum of all the 6 square areas.
Answer:
Step-by-step explanation:
From the information given,
p represents the probability of success.
x represents the number of success
n represents the number of samples
Therefore,
1) b(x|n,p): b(3|8, .35)
x = 3
n = 8
p = 0.35
From the binomial probability distribution calculator,
P(x = 3) = 0.28
1) b(x|n,p): b(5|8, .6)
x = 5
n = 8
p = 0.6
From the binomial probability distribution calculator,
P(x = 5) = 0.28
c) n = 7
p = 0.6
P(3 ≤ X ≤ 5)
P(x ≥ 3) = 0.904
P(x ≤ 5) = 0.841
P(3 ≤ X ≤ 5) = 0.904 - 0.841 = 0.063
d) n = 9
p = 0.1
P(1 ≤ X) = p(x ≥ 1)
p(x ≥ 1) = 0.61
Given: PQ=2x-3. if QR=5x+7 and PR=10x-11
To Find: PR
Solution: From the attached diagram, point P, Q and R are co-linear.
Hence, PR = PQ + QR
or, 10x-11 = 2x-3 + 5x+7
or, 10x - 7x = 15
or, x = 5
Now, we shall calculate the value of PR
PR = 10x-11
or, PR = 10× 5 - 11
or, PR = 39
Hence, the required value of PR will be 39.
For #1 it is $1540. For #2 $7.50.
