A and X are two independent events , Option A is the correct answer.
<h3>When is Probability ?</h3>
Probability is the likelihood of an event to happen
A two way table is given
The two events will be independent when
If A is the first event and B is the second event , then
P(A) = P(A|B)
Here the P(A) = 30/100 = 0.3
P(B) = 20/100 = 0.2
P(A|X) = 15/50 = 0.3
P(A) = P(A|X)
Therefore A and X are two independent events , Option A is the correct answer.

Step-by-step explanation:
Answer:
The answer to your question is: 3780 m²
Step-by-step explanation:
Data
Rectangular ceiling
base = 63 ft
height = 60 ft
Formula
Area = base x height
Process
Area = 63 x 60
= 3780 m²
Step-by-step explanation:
You have to use logarithms.
1) a = log_3 (1/27) = -log_3 (27) = -3
2) b = log_3 (9 * 3^(1/2)) = log_3 (3 ^ {5/2}) = 5/2
3) c = -log_3 (sqrt3) = -1/2
